So what are the rules about calling crusades and the crusader states. Can we call them anywhere, can they join them? There didn't seem to be a decision made last time this came up and I can't complete my turn until one is made.
I think allowing any target for crusades or Jihads is a good idea because there is a set list of available targets in the game, and not all target cities appear on this list.

As to the Crusader States, it doesn't seem fair for them to get to cancel out our crusades, but it also seems unfair that they lack any type of crusade/jihad mechanic. What do you guys think?
