There's another epic Humble Bundle on this week incase you misses the Codemaster bundle. This is one for the Civ fans.
Not only do you get the complete editions of Civ III, IV and V but you also get VI! all for $15.
Okay, I made that last part up but you get to play with plains, tranes and portable parrot stands instead!
