Command and Conquer 3 (my high school friends have a yearly tradition where we do an 8-hour C&C marathon between Christmas and New Year.)
Team Fortress 2
Call of Duty 4 (kick ass game – finished the campaign in an afternoon)
Gears of War
The Witcher (still playing — load times are horrendous but the game is solid, like you’re reading a novel)
As my calendar is slowly getting filled with new appointments for January, I slowly bid goodbye to a lax December. It was fun while it lasted.
