I like the idea of using a microphone. Just imagen playing as Abe, you can speak through him with the microphone and literally say anything you want and the inhabitants will respond with good understanding on what you are saying. You could boss them around commanding them to do anything you want, or you could lie and confuse to the characters to make complicated situations, or fool your emimies on getting secret information. It'll reach the limit of Gamespeak, but it'll need a hell of alot of AI to make this possible.
I'm thinking of PS3, mulitiplatform would be best for everyone, but I personaly would like it to be included on this particular platform. PS2 had many exclusive titles which I wanted to get my hands on, but I never could.
