Actually, I was directed there by someone on YouTube called TheArchfiend who was slamming Irate Gamer for being an ass. I've checked out a few of his videos and then checked out AVGN's stuff.
Yeah, he copied, but what really got me was after people started going, "Dude, you're copying AVGN!" he'd deny it, delete comments on his videos that said so, and was all around pretty stupid about it. He could have salvaged at least a little reputation by owning up to it, but instead kept denying it and, if I remember correctly, went to far as to say that Angry Video Game Nerd was copying off him.
I just laughed at what an idiot he was.
