he's really terrible at games, I cannot see him playing something fast paced and multiplayer like tf2, there's just wayy to much going on, he would instantly be overwhelmed and probably ragequit immiedately. I really could only see him playing a useless engi who does nothing all game but repair shit at spawn, or suicide rush with a pyro repeatedly.
I honestly cant even imagine him playing any game on a keyboard and mouse, especially no games that require quick reactions and precision. He lacks both of those essential skills and if history has shown us anything, Chris does not learn and certainly would never get better with practice.
