Choose one. Not to say that there aren't any good FPS on the market, but military shooters are slowly over saturating and killing the market. Seriously, we need to make a return to arena shooters and the like.
That said, I think it'd be cool to see an FPS from a Japanese developer. I hate to say Platinum should make everything, but it'd be awesome if they did.
Currently Playing: Far Cry 3, Darksiders 2, and Vanquish. Anticipating: MGR:R, Bioshock Infinite, Pokemon X and KHHD.
Japanese devs are innovative? When they aren't making awful Gears clones, they're making the same few games they've made for a few decades now. They fear change, which is why all of their RPGs, and the characters and stories in them, are the same.
