Indeed, he's a talented VA. He was actually the voice of Abbas in the original AC, and I have no idea why they didn't let him reprise the role for Revelations. It has to be cheaper to have one VA instead of two, doesn't it? Even if one is Nolan North. Also the crap turrets and corrupt cores in Portal 2 were him, which I never would have guessed without looking it up.
But despite that, devs do tend to ask for his "Drake" voice over and over. Kind of a shame, but I'm sure it's a (very comfortable) living.
