Travis was getting pretty dark at the end of the first game... I'm sure his character will build up to that. Sorry for doing this comparison, but it's like with Vash in Trigun, he can be pretty stupid at times, but when it gets serious, he's furious as hell!
With that said, I have no worries about the humor in the game. I mean, Suda51 IS developing the game!
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
