Multiplayer Warband is fun, if you haven't tried that yet, it may keep you going with the game awhile longer. Personally it's one of my favorite games, but there are so many computer games out there I'm sure you'll find something that suits your fancy. Play GTA (Grand Theft Auto) games for an open world sandbox. San Andreas was fun and you can probably get it cheap somewhere. Though those games were a bit too much random homicidal violence for me after awhile, they are entertaining. ;)
