Well, in my most recent game (early, normal, spain, GA, medmod abbey road version) it;s a completely different story. Much of this can be put down to the medmod (this is the one that doesn't change unit stats much at all, but gives the AI lots of helping hands to play well).

The english and french have never ladi a finger on each other, the english lands in france are still help, and both have advanced on german lands a little but they have never been to war with each other in the past 100 years.

The poles and hungarians ganged up on the germans (with help from both french and itialians) and wiped them out, then bickered over their lands untill I cam along and smashed them both into one province each. They are still fighting each other.

The egyptians and turks have squabbled a little, but now the egyptians are concertrating on trying to retake the crusader provinces (one held by france, one by england and one by me, the other is still egyptian) while the turks and byzants are still duking it out, sometimes reaching to constantinople while the byzants have expanded into formerly polish lands, and a little north aswell.

The novogrods (called kievins in abbey road medmod) have done amazing things. They lost most northlands to rebellions, and immediately proceeded south to take on the byzants, most of the polish lands and even striking out against the turks. This may all change when the horde arrives, but they have the strength to hold out for a while.

The danes actually took norway and finland, had a few german lands breifly, but have moved back and are actually trading.

The itallians almost wiped out the almohands and would have kicked the egyptians had I not stepped in, they also took ALL the italian penisular apart from malta and have been bickeing with the pope for quite some time though I put a stop to that.

The aragonese have been fighting for control of naples for over two decades against the itialians, and have not once attacked me (the spanish).

And EVERY faction has at least 5 boats in differnt sea regions, some (the itialians and french mostly) have nearly as big a fleet as me, but are not fighting naval wars unless excomunicated or against me.
