User blog comment:Pandoo/What's the game you've played longest?/@comment-5215338-20140804231818

Team Fortress 2, 656 hours logged on Steam. None of my other playtimes come even close to that number.

My longest played single player games are Sonic Generations for 38 hours (honestly, I think I've got more than that), and then Assassin's Creed II for 27 hours.

Expecting Payday 2 to reach 100 hours by the end of August at the rate I'm playing.
