I usually only play the Early period, so I can't say for sure...

I can guarantee that the Italians and Russians will do nothing. The French will defeat the English. The HRE will be eaten by Huns/Poles/Danes and maybe French. The Spanish will die alongside Aragon as Almos range into southern France. Egypt, Turks, and Byz will do a little dance and the Poles will forget why they came.

Or at least, that's what usually happens in my experiences. I'd say a good 60% of the time. Although, I haven't played in over 3 years. Until this week. Found the XL mod and started a Serb campaign. Very nice, very nice... I was going to do my first AAR on that, but the girlfriend thought my notes were trash. So I started a new one with Danes. Will begin posting it in a couple of days. I'll let you know if I see any superpowers there.
