Both animes play in an MMORPG world and have several similarities 
report Recommended by Atira
The story line involves the idea that you enter a world that is a virtual reality. They have similar art styles and the game play for the characters is different, but the real world repercussions are more drastic in one series then in the other, but they are still there.

Both are about a guy that is forced to play a game risking his live together with other people. In order to leave this situation, they have to beat the game following the rules they were given.

It comes as no surprise that the environment and concept of these two series are analogous to one and another. Having the same protagonist voice actor in these two series undoubtedly strengthens the momentum going forward. 'Sword Art Online' and 'Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka Similar' focus heavily on game systems, leveling and battle strategies. Through layers of boss flooring that increased in difficulty as you progress further which is accompanied by rewards, it is something that is welcomed by fans who has a certain connection with gaming. By all means, the comedy and romance are there to provide joy in  read more

Yes, both main characters are being transported into a gaming world where there are lots of mysterious wonders to explore. 'No Game No Life' is fresh in terms of its fanservice comedies and vibrant colours, whereas 'Sword Art Online' is focused more on the hardship of the main character and everyone else around him while developing strong romantic relationships along the way. Comparing the storylines, 'Sword Art Online' easily takes the cake but the crazy and fun games of 'No Game No Life' is something to smile about.

Game mechanics are important as the setting of the animes. They place importance on life or death in HP, and remain as a character's lifeline throughout the whole anime as a game mechanic. The game's nature is fantasy. Swords and magic skills are decided.

As the king of the faux-MMORPG arena (.hack started development in 2000, then released in 2002; SAO was first wrote in 2001/2002), .hack can claim a lot of the responsibility for SAO. In the anime universe, the idea of being trapped in a fantasy virtual reality setting, via playing a MMORPG, is already 10+ years old. Even Yuki Kajiura's wonderful (though underwhelming, in SAO) music became famous as a result of her best-soundtrack-ever work on .hack//SIGN.

A group of people are thrown into a fantasy world from which they cannot escape and must fight to find a way to survive. Though comedic at times, the plot is relatively serious and focuses on battles, life and death, and the bonds between characters. Both are also by A-1 Pictures, so their art styles are somewhat similar.

These feature skilled gamers in fantasy MMORPG settings. Though the plots differ considerably, there's no shortage of similarities in other regards such as the engaging action sequences, the very skilled and confident protagonists, and the cute female companions.

Something that people enjoy is turned into a living nightmare and it involves technology. A character who is unable to make friends is suddenly able to make friends only to lose them due to the "game". There is also a "god" in the game too.

Fantasy world with fighting with themes of what its like when a real person is thrown into what feels like a game. After SAO I looked for other anime which felt similar Re:Zero was very satisfying.

Yes, it's another guy stuck in a fantasy world however it's a more light-hearted take on the genre. A bit lewd at times but still generally wholesome. While Konosuba doesn't take place in a video game, it captures the world of an MMORPG quite well. In a way that SAO didn't in my opinion.

In both series the main characters are trapped in a world where they would rather not be in. They try to resist and fight this world in order to regain their freedom. This is why I would recommend watching both series if you liked one of them. Both of them also involve a love story

Both MCs feels that they need to do what needs to be done on their own by there own way. Even though they some what dislike the choices they've made they know that the can persevere over whatever trails they face. They both work hard and are willing to scarify themselves to benefit others.

Well... What can i say about Sword Art Online and Darling in the Franxx? First of all, Asuna Yuuki and Zero Two, the main female characters of SAO and Darling respectively, are voiced by Haruka Tomatsu. Also both main girls are the biggest reason that both animes are pretty attractive to the casual anime fan, also Asuna and Zero Two hold the quality of the plot. Kirito and Hiro, the main male characters, are the perfect complement to the main girl, but have several defects due to their closed environment. The main difference is that Hiro is more "normal" and Kirito is more OP. From the back side  read more

Mahouka and Sword Art both have an extremely competent and multitalented protagonist, who is usually quite level-headed. The protagonists each have a younger sister who is a serious brocon. Both series are more about hiding ones full potential and deciding where to go all out, rather than falling into a desperate situation.

A person decides to play God within a game where people can interface with a virtual reality. If the God's rules aren't met people die. Basically, very similar situations between the two games. There is also the question of "why" anyone would do this and if they have a reason for being so cruel. 
report Recommended by Yemi_Hikari
The original base goal of the anime are both the same, to reach the top of the tower. However, SAO setting is a fantasy based virtual game, while Druaga is a fantasy setting based on a game. Though it may be spoiler-ish, the second half of SAO and the second season of Druaga are also the same, to find/save someone. There are also minor scenes that may remind you of the other anime like the boss being CG'd or even the tentacle scenes... lol...

Both are VR-MMORPG games where the player puts on a headset and sets foot into a different world in their own adventure! After that, the story tends to differ (for now).

Both main characters are somewhat fictional in the world that the action is taking place, deal with swords and increasing inner strength/ skill. Also, in both shows the art and sound are great.

The entire .hack series is a precursory work to Sword Art Online in the fact .hack was one of the first series to come out for the virtual reality genre, but is also one of the better known earlier works. This particular .hack is short, allowing a quick consumption for those starting out with Sword Art Online and wanting to expand their horizons into the .hack series, but on the flip side, SAO provides a twist on what .hack helped to make popular.

Both Anime center around sword fighting and mythical creatures. The main character is on a quest to make himself stronger and wants to become the best in order to complete is life goal. They have to learn how to survive and make new allies and friends in order to achieve their goal. Do you want a story full of passion, friendship and epic mindblowing battles? Than you should watch these series.

Both represent literally every A1 Pictures light novel adaptation cliché. In fact, TAW feels like what SAO would be if SAO took place at a school instead of in a video game world.

Ok so this is kind of a stretch because the settings in SAO and CSR are totally different: one being inside a MMORPG and the other a post apocalyptic world with moving cities. However they are very similar in the sense that the main characters between the two are both total badasses. Kirito being a solo player on the front lines who doesnt need any help and Layfon being one of the 7 heavenly blades or whatever in disguise at an ordinary school/city.

In both anime, our main characters has friends/allies who help achieve his goal. We see his ups and down but always goes back up. Add some drama too.

These two titles both did quite well for their first episode release, as most of us know, one more than the other. What binds these two together in my opinion, is the fact we have a very strong male lead, who seems to be quite powerful to the point we can assume most fights in both shows will go in favor of the main character. Now, both series try to mask this sense of Over Powered-ness, which offers some nice action scenes. The plot has some similarities, like the mortality of every character, which can be exploited in both series. These series are not averse  read more

But most importantly, both have excellently developed characters and take place (mostly for SAO) in a fantasy setting with some real world elements (SAO is occasionally set in modern-day Japan whereas HxH is set in a completely alternate world very similar to modern-day Japan).

Clannad (+Clannad After Story) and Sword Art Online are similar in one significant factor. Unlike the majority of animes with romance these two show's actually develop their main's characters affections for one another and you get to watch them grow in their relationships, as well as deal with various trials and tribulations. Overall, if you felt that either relationship (Kirito/Asuna or Nagisa/Tomoya) was fulfilling, I believe you will enjoy watching the other one develop as well.

While both series have completely different premises, both are almost identical in any other aspect. Both have bland and boring Mary Sue protagonist, who excels at literally everything despite barely having any expertise or training and exhausts all potential for character development by the end of 1st arc, have amazing visuals at the cost of lazy writing and poor cast of characters, tries to tell some deep story, but fails miserably at this and are seasonal, but still long running. In short: If you loved SAO, you'll love Symphogear. But if you hated SAO, you'll hate Symphogear as well.

Then one becomes an actually decent story of a love triangle while the other one devolves into a threesome, wait no, foursome. Wait. Fiv- UHH I lost count! Props if you can tell which is which.

The story line involves the idea that the main character must seduce girls with the help of a virtual game applied in real life. These girls are spirits that need to be saved or they will be killed. Anime with good plot, romance and action.

Both of the anime got amazing action scenes. Sword art online is about a players trapped in a game and Kyoukai no Kanata is about fantasy where a creature called "Youmu" exist. Both of the anime got male and female main characters who develop feeling with each other.

Despite what people think, Kirito, Asuna, and the others did rely on team work like the main crew of characters in Alderamin. Both main characters seem to be good at assessing their situation and acting accordingly. The majority of the time, their plans come through.

They're both similar quality and easy to watch. If you liked one, you're probably the target audience for the other.

Without spoiling too much, both of these do have similar settings and moods. They both have very well animated fights, fantasy/sci-fi settings, and both begin with a fairly large plot twist (though if you didn't see Sword Art Online's coming from a mile away I don't know what you were watching). They both have their flaws, one more than the other, but are enjoyable fantasy series nonetheless. Deca Dence has a bit more of a message to say, but if you are looking for something fun and enjoyed one, you might like the other.

Based on an MMORPG. SAO uses Nerve Gear VR technology. While Blade and Soul is for the PC. One series deals with players trapped in a game. They must find a way out or risk dying in the process. The other series is based off a Korean MMORPG. More action and fanservice. SAO has swords. Blade and Soul has martial arts. While SAO has action and plot driven. But also has romance and drama between main characters and others. Both series has overpowered main character.

I'll start by saying that these are different in a lot of ways, but the overall feel and some of the themes are the same. SAO only touches on what Maoyuu Maou Yuusha is all about. While they both have some cool action here and there (SAO has more than Maoyuu Maou Yuusha by far, which isn't a lot if you've seen SAO), they both deal with bigger themes and they are mostly about the relationship between the lead male and female characters. They both are midieval themed with some magic and monsters, and the main character in both is the strongest fighter in the land.  read more

The anime is similar to SAO mainly due to clearing dungeon levels as a group of adventurers and having the main character to be more powerful than others and also having a bond with other characters while clearing dungeons.

I was very surprised to find that these weren't already recommended for each other. I can say with confidence that if you like one, you'll most likely like the other. both deal with gaming turning into something more real. although the game subjects are different. The art is really similar in both.They are so similar on atmosphere, that you must watch both. I MUST stress on thing though, if you are into SAO for the fighting, you may not like the other, for it has much less action. it has more ROMANCE.

The main characters from both series are refereed to as Black Swordsman. But Kuusen adds Black Swords master instead. Both are voiced by Matusoka-san. Both taking place in a fantasy setting. But in SAO's case its an VRMMORPG video game. While in Kuusen Madoushi takes place in a magic school setting. They are called a traitor by other people due to their actions. They are surrounded by woman who are interested in them

I know the plots are completely different but the feeling that both the anime transmit are the same. Both anime start with the main characters living a happy life when they both enter a new world (for mahou shoujo that would be the world of witchs and SOA the online game of the same title) that at first both those worlds feel like paradise, full of hapinness but soon after they realise not everything is as good as they tought (even though in SOA this happens way faster and right on the first episode) and after that they live in a life full of dilemmas  read more

1.) It has the whole medieval sword fighting fantasy thing going on (Though in Escaflowne there are mecha) 2.) It has the same dynamics with action, fighting, and romance. 3.) There are trapped in other worlds and trying to get home. Hitome, from Escaflowne, tries to get back to earth and everyone in SAO tries to leave the vitual world.

When i watch SAO. it remind me an arc in yu-gi-oh when they are both trapped in virtual world and they must beat the game i mean boss behind this. Also both anime have a cool tech. Ex: Yu-gi-oh have a duel disk it can materialization monster and SAO have nerve gear so we can play inside the game.

Same concept but Abenobashi is implemented better, boy and girl trapped in a fictional world fighting to return to reality.

Both are about people who love playing online games where they end up finding their love interests and also eventually meeting their real life counterparts.

No recommendation for this yet? Well, old school series like Digimon Adventure probably slipped out of some people's heads. But at any rate, these two series have quite a bit in common. Both series features sci fi themes involving a deep journey to another virtual world that blurs the lines between fiction and reality. In that fictional world, there are digital like beings. Both series has main characters who are independent, skilled, resourceful, and helpful for those in need especially for their friends. Both series has comedy, drama, action, and a game atmosphere setting. Both series sets the fictional world with similar aspects such as the city, ocean,  read more

Both Sword Art Online and ZET are very fast paced series, and they both contain fantastic action scenes, but ZET is much more for a mature audience out there.

The story progresses the same you know. The main reason because both start with an awesome plot of combats until the characters reach the top. But it is not seen completely because the plot decides to go to another route. So there will be a bunch of side stories than just wathcing the plot they have stated in the first episode. By the way the first episodes of each one is almost the same I recommend it if someone wants to watch it.

The main characters are stuck in a video game and must clear the game in order to leave. Death is also permanent. Sword Art Online is a virtual reality video game played using NerveGear; the log-out button has been removed from the menu, leaving clearing the game's 100 levels as the only way out. Greed Island is a rare video game that only Hunters, who have a special power called nen, can play; players who start the game are transported to the actual isla
