I previously posted about AI Only games of Civ 5- here is the biggest one of all. The battle royale is a civ AI Only game of Sid Meier's Civilisation 5, starting on August 10th. 61 Civilisations are fighting in a domination match - the twist is that they are all AIs.

If you want to get involved, pick a side and cheer for them in IRC (#civbattleroyale on freenode), reddit (/r/civbattleroyale) or twitch (stream at twitch.tv/tpangolin, times to be announced). Alternatively, I'll be checking back on this post so feel free to discuss it here.
