I'm sure GTA has been suggested before, but honestly i'd like to see Pewdie play these games. The insanely random weird things that happen in GTA online at least, make it the funniest game I've ever played. Many times me and my friends have ended up crying because we were laughing so hard. One time, our friend laughed until he got sick. I think if Pewdie played it with Cry or something, it would be a very good watch.
tl;dr - Pewdie and Cry (OR DOPEFISH!) would make it really funny
Now, Tony Hawk Underground or Underground 2 are pretty fun games in my opinion. I believe this might have already been suggested.
Guitar Hero.... this game is one of my all time favorites. Every knows about it, but if you actually haven't played it, you should. If you're not good at the game, it'd still be funny to see a video of you dancing around missing all the notes.
If all of these were suggested, which wouldn't surprise me, consider this a formal bump.
