I originally wanted to do a summer season anime thread but then i realized that probably nobody here watches new anime.
But this is something that might interest you, it's similiar to the .hack series where in the future people play games through virtual reality including an MMO called Sword Art Online, however they end up getting trapped in this world and removing the virtual helmets will result in them dying, the only way to get out is to finish the game.
I personally don't like it and it's pretty poorly done IMO but i think some of you might like it.
