Bethesda today posted a neat video in celebration of Wolf's 20th anniversary. It's John Carmack first giving a bit of history of the game and then giving a rolling commentary as he plays the first couple of levels, really interesting stuff! Also, he has a hilarious little nerdish laugh that often ends his sentences.
yeah the guy talks a bit funny. i heard him in a documentary once and he has some weird thing with his voice, i cant really explain it. its cute though probly a side effect of nerdism.
