Since this game just came out I think it's fair to bring it up in case PewDie hasn't noticed its release. I'm mostly a multiplayer guy because I usually need more from a game for it to be fun but in my opinion Hitman: Absolution is one of the best singleplayer games I know (I have played and finished it with great joy).
Basic Info:
Hitman is a stealth based 3rd person shooter game where the objective is to kill a specific target(s) and/or escape the level (there are many levels). The mechanics and graphics are very realistic and you earn more points for finishing the level without anyone seeing you. There are many ways to kill each target on any given level and although you are awarded more points for being stealthy there is nothing stopping you from grabbing a shotgun and shooting everything in sight.
Why this game?
I think it would be very fun to see how PewDiePie goes about completing every level. The game offers an interesting environment and a good story, with PewDiePie's commentary and playstyle I think it would make for an amazing playthrough, very fun for both viewers to watch and PiewDie himself to play. It would also be fun to see him try complete a level stealthy, fail, rage, give up and just shoot his way through
