This game will be played in Civilization IV Beyond the Sword, version 3.19, using the standard BUFFY-3.19.003 HoF mod.
If a later BtS patch is released during this game you will NOT be able to use it to play. You will need to complete this game in BtS version 3.19 before updating your copy of BtS, or create and update a separate copy.
Macintosh players can only join in if they are able to run the Windows software on their system.
