Steam is having a sale on Civilization V this weekend for $7 or Civilization V Game of the Year for $12. I got the GOTY Edition that comes with a plethora of extra scenario and map packs. You can also play the game for free until Sunday at 1pm Pacific. I haven't played Civ in years. I forgot how fun it is. Also on sale for $9.99 is Red Orchestra 2: Heroes of Stalingrad. You can also play it for free this weekend.
