Man, Matt has been grating on my nerves as of late. THere was the Sonic Adventure play through where he was drunk and super negative throughout the whole thing. He was also similar to that during Star Fox Adventures. Then there seems to be times where he just plays badly on purpose, feigns inability to play, or just straight does stuff for no good reason (like in the latest UD episode where he just refused to pickup the clue, Pat wanted to see the back of, again. Liam even semi called him out in the latest Mystery Box where he was like "how about you try and do something as opposed to nothing at all."
When he cares about something, like Rustlemania he goes all in but when it's something he isn't feeling he just seems to phone it in.
