- Christians vs Muslims vs Mongols on the Crusades map? This probably means CA has to implement permanent alliances - I just hope they're flexible enough and we can control them through scripting
I think you can do this now by making faction or group specific AI profiles which stop them attacking particular factions. It would be a cool way to handle the RTW thing of bactria/parthia emerging from seleucid satrapies after x number of turns.

I hope so. I really liked that system and wasted all evening realising it didn't work anymore in mTW2 :)
