I simply don't believe that statement. I believe that NIS made the statement. Not questioning that. I'm questioning their ability to gauge such a thing. I'm sure the right people with the right talent and the right amount of money could have *easily* made Disgaea 3 work on a PS2.
Seriously. I mean, can't you run a Deep Blue-style chess program on a PS2? Are they suggesting that the game is more complex than chess? I don't believe that for a moment.
