I've been a fan of the .hack franchise for quite a long time. I came to it through .hack//Sign in high school and followed it into the games, exploring the other animes as they came out. So when I heard the announcement for .hack//Quantum I was very excited, but after the initial character design shots I was skeptical. Female characters of both Kite and Balmung, to me, screams unnecessary and pandering to fanboys; and adding a character whose literally Blackrose with a different hairstyle really annoyed me as it seemed extremely pointless and lazy. However I eventually downloaded them and sat down one evening to read more

The existence of .Hack//Quantum immediately brings up the question: How many damn times will Namco Bandai rehash the same story in the same franchise?

STORY: Once upon a time, there was a video game company that made a really popular online game called The World (Though in the real world, the game that is housed within the game has a very questionable popularity, as in does anyone really care for .hack anymore?), the game was an incredibly flawed game where hacking is the only way to do any cool shit, and strange phenomenons that cause people in real life fall unconscious into a coma like state, read more

I saw this on Netflix and watched out of pure curiosity since I've seen some of .hack//SIGN. It's a solid OVA with likable and funny characters and should be watched by any fan of the series. I think that five episodes would have sufficed for this story because even though it was and OVA, they built a good story from the first episode and the two episodes afterwards felt rushed towards a somewhat incomplete ending.

Having followed .hack since the days of .hack//SIGN it's pretty safe to say I'm quite the fan of the franchise. I've seen every anime installment out there and I was actually excited for this. While mixed feelings of Kinmea Citrus taking over from longtime.hack// animation house Bee Train I was wondering how a new studio would take a new anime and I can say it's a fun and entertaining watch sure to be accessible to newcomers but may be a bit of a turn off for longtime watchers for my self.

Animation and art wise Quantum was certainly sporting production values lacking from some previous installments read more

Anime: Sword Art Online
These two anime use the same concept involving a MMORPG game where minds of players can be trapped inside.

Anime: Accel World
.Hack//Quantum and Accel World are both "game based" animes. They have both a really good story and very nice character design. The animation are similar, they look both pretty good. If one is looking for a good anime, a good story and some nice animations, I would recommend anyone to check out both of these animes. 
reportRecommended by Barrosy
Anime: Summer Wars
Both of these anime are centered around a certain game. The main protagonist of each anime has done something by accident resulting to damage of the game's order that caused disruption to their real lives. A mysterious character appears after them whom they have to fight through with to return the game's equilibrium and reunite with each other.

Anime: Tsubasa Chronicle
.hack//Quantum is the Tsubasa of the .hack universe. Many of the characters are similar to their counterparts and somewhat follow in their footsteps. .hack//Quantum is a major treat for fans, but still accessible to newcomers.

Anime: Ghost in the Shell: Stand Alone Complex
The ethics of cybernetics and the boundaries of the human mind are themes that are explored in both franchises. Corporate or governmental conspiracies related to the usage of futuristic technologies are a major themes in both series. Cyberbrains (GitS) or data chip implants (Quantum), if you like a good mix of SF with action, you'll enjoy both series. Note that .hack is a much light-hearted version compared to Stand Alone Complex, which is for the more hardened viewers.
