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

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

Welcome back to “The World,” the MMORPG that forms the core of the extensive .hack franchise. In this iteration of the franchise's single plot, school friends Asumi (Sakuya), Eri (Mary), and Iori (Tobias) enjoy getting together in the game's virtual existence to explore new territories and fight bosses. When Sakuya accidentally interrupts a guild's planned boss battle, she finds herself with a price on her head. This leads our trio and the players after them to a strange, dark corner of the game, and some of the people fall unconscious following an encounter with a mysterious black PC. The remaining characters must, of course, find read more

I've never watched any .hack before, and I have to say that changes my mind.

The plot is really simply, but I think it's that which produces this anime so light! I mean, Even if some passages is a little alarming or maybe stressful, I found the background very relaxant. And in spite of the story is fantasy, I found the plot rather constructive and not far-fatched.

This anime offers us a really good design. Yes, I was surprised that the graphics are so well. Due to the extracts that I saw the others .Hack, I've found .hack/Quantum upper at all of this. The graphic is fluid, read more

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

SAO = .hack//Quantum. Simple as.

-People use virtual reality devices.
-Protags are stuck in game along with others.
-Die in game, die IRL.
-Created purposefully by one mastermind.
-Only some people get out alive in the end.

All in all, SAO is like 9001 times better, longer and more thrilling. But this is literally the same, except in .hack protags are girls and aren't OP.

.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
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.

.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. 
reportRecommended by abblondie
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.
