there are shitloads of worthwhile games that get play in Japan but never see the east. I don't see anybody pushing many of the scads of weirdo puzzle games, genre mash-ups, shooters, and less famous RPG's that so heavily populate Japan here in America.
Atlus does a great job, a very great job, I'm not disputing that. But to say that there's nothing left over there to bring out here is just plain silly. What's more accurate is to say is that the future market is changing drastically. Its always been a nickel and dime business selling Wacky Jappy in America. NIS, Atlus, SNK, Konami, and occasional contributors Mastiff, D3, Square Enix, Majesco, Agetec, Ubi Soft, and more, are taking up all the Japafag money to be spent. There's still lots of games out there that I'd want to play that don't come out here. But the market for niche tastes is crowded as hell.
What I want very badly is a publisher who publishes the puzzle and action games, leaves the angsty teenager RPG's to the other guys. If Gajinworks does that, they will have themselves a steady customer right here.
