Sword Art Online is an anime about 10,000 gamers trapped in a VR MMORPG where if they die in the game, they die in real life. So of course it was only a matter of time before they made a game about it. Unfortunately, if you aren't already a fan, there is little in this game for you but boredom.
Sword Art Online was easily one of the most popular anime of 2012. And while the West never got the first game, Sword Art Online: Infinity Moment, on the PSP, it will be getting the updated version of the game, Sword Art Online: Hollow Fragment, for the Vita later this year.
