The stuff he's done regarding raising money for his movie. Asking for $75,000, hitting that mark then asking for $250,000, then $300,000. Then he started asking for free locations to shoot the movie and asked to borrow different things from people.... After they just gave him $300,000.
He's also done some weird stuff like deleting comments on YT, removing ratings and comments entirely when he didn't like what was being said. There was some hypocritical stuff going on there I guess, I can't remember the whole story.
And in general, he just seems a bit full of himself. I've watched him interact with people and I've heard stories of him being a complete dick. I also don't buy he's that much of a gamer. This is the same guy who claimed you couldn't use a controller on a computer or sit on a couch and get comfortable and made several more ignorant comments about the PC as a gaming platform.
