It's VikingHorde's new XL update (143MB). I couldn't wait to dive in as the Knights of St John and in GA mode too .

I managed to capture Cyprus and wrestle Tripoli back from the English (who were meant to carry their crusade to Antioch but found Tripoli more to their liking for some reason .) The poor Egyptians really have had a hard time as the French now occupy Palestine and Arabia, Spain has Antioch and Syria, I have Tripoli, and the Armenians have Mesopotamia (a new province included in the mod).
