It's almost over but if you're fast (10 hours left) you can pick up
- Europa Universalis III Complete
- War of the Roses: Kingmaker
- Warlock: Master of the Arcane
- Leviathan: Warships
- Dungeonland
- The Showdown Effect
for any amount you want. Beat the average (about $5,80 now) and get Magicka and Crusader Kings as well.
If you don't have EU III this is a great opportunity. Warlock had been discussed on the forums, it's a modern Master of Magic (civilization in a fantasy setting).
Magicka & CK II are great games, if you don't have those then paying more than the average for these games is really worth it.
