What's this? Did I miss some drama project thread again?
Look, I like Sonic and Disgaea too, and hey, if you can do this and make it decent, well, good for you then. But as it stands now, there's nothing here except for a list of characters who you want to be in the game. That's like me saying I'm gonna put Cloud, Red XIII, Dante and Vergil from DMC, Chaz from PSIV, and myself into a game. Doesn't mean I can do it, or even make it look good; in fact odds are the complete opposite since people already know what those characters look and act like in their own stories. You have to be -extremely- good to get a crossover game working right, and frankly, without any screenshots or proof otherwise, we're going to assume it sucks ass like every other project idea that's attempted to do this.
