Team Fortress 2
Remember when Team Fortress 2 turned into a sparkling, cheerful extension of the Pyro's demented psyche earlier this year? I was happy to be reminded by Rossrox' glittery and violent portrayal of the conflict. I especially enjoy the fact that TF2 has chosen this moment to remind players to be respectful to one another, as a soldier lies burning to death on a floor, and another readies a rocket launcher against a charging Pyro. It's important to remain polite in the face of impending doom. Jolly good show.
