Those weather changes sound like a more intense experience of the battlefield, maybe this will remind us the rainy maps of Shogun. It would be nice to see more snowy maps, I hope you find the parameter. I totally agree with the removal of river maps, and more desert maps is always good, I love desert battles :)

I've played a few turns more this night and as I said above the Aragonese declared war on the Egyptians. I launched two victorious crusades against Granada and Morocco, and defeated them on the sea. The Egyptians had strong armies but an important factor played against them, the sultan was isolated in Ireland (they also had conquered Scotland and Wales). So after I attacked them, their provinces suffered a severe loyalty penalty with the consequent civil war and the reappearance of the Almohads in Tunisia, Algeria and Cyrenaica. Now I'm the main superpower of the game in terms of army and cash, so I reached the point when a campaign begins to lose interest for me, however it costs me a lot more effort. Maybe I'll use the -ian to play other faction in this same campaign.

I would like to do a minor criticism after today's experience. As in vanilla, the possibility of silly invasions is present and AI factions can suffer penalty for having their leader isolated. This occurred not only to the Egyptians in my campaign but also to the Byzantines which had all their royal line isolated in Crete. How do you think that this could be solved?
