Theres a free japanese third person shooter mmo called Ai Space. One cool thing of this game is that it has replicas of cities (at least it has some of Akihabara, I havnt played it alot to see what else it has). One cool thing is that is has niconico douga videos playing on the walls of some buildings (kind of like youtube). The only annoying part is that its arrow keys instead of WASD but actally you can probably change that somewhere in the settings. Uh its crazy anime style so you get a pet anime girl for whatever reason. I'm not sure since i havn't done too much but I think whenever you go into a mission or whatever, you play as her. Also it seems to be cash shop style, but if you want to buy anything, I think it will still work because the site looks like it says they take visa or mastercard. This game is so weird, as you damage enemies (the girl enemies not the random monster enemies) they lose their clothes, and the same thing happens to you (your ai) when you get damaged as well.
