SP:
1. Chessmaster 10th Edition (so I can finally learn to play chess decently)
2. Oblivion (and the TES-Toolkit off course, so I can make more Oblivion for myself)
3. Gothic (simply love it)
MP:
1. Anarchy Online
2. World or Warcraft (never played it, but this seems about the right time to get started)
3. Call of Duty 2
