Tired of this?
Does a Jihad army sitting in a boat in a lake next to Jerusalem make you utterly sick?
Do you think that masses of armies standing idly beside a single city while one army sieges it, does not quite represent the epicness behind crusades?
Are you tired of seeing crusades/jihads that, even if successful, end with some faction losing the city as soon as the Crusade is successful, and no other changes take place in the region?
Well then listen up!
I believe Crusades should be accompanied by an event called Pilgrimage.
Pilgrimage would entail a large group of high piety priests/imams spawning at the epicenter of the crusade/jihad and then being scripted to convert provinces within the general vicinity of the Crusade/Jihad. If these priests are allowed to convert a significant portion of the populace, the outlying provinces will become of the faction that took the city upon which the crusade was declared, and then held it for at least 5 turns.
This would not only make jihads/crusades actions to be feared, but it would also help to shift the power balances in the regions and make the ai more unpredictable so that the political map is not the same every single game as it is now!
We may not be able to fix the ai, but this is the 2nd best option I think and will have the intended effect that we all want crusades to have: Total chaos in the regions effected.
So I call upon you, people who grow tired of the ineptitude of the things this entire game was based around, to cry out passionately for this thing! (or at least discuss the possibilities)
If you have modding skills feedback on the positives/negatives/overall implementability of this Pilgrimage idea it shall be much appreciated!
