I've noticed that at the Austrian Spawn, Hungary has expanded into their spawn zone so they start at war. 9/10 times, the Austrians vassal or control almost all of the Hungarian Empire(not ahistorical by any means).
France has a great knack with taking out Burgundy, but Burgundy ends up settling(or conquering) parts of Germany, making France collapse.
Ottomans mostly conquer Constantinople and collapse Byzantium, but seemingly wants to expand further into Europe rather than the Middle East(even when Arabs are collapsed).
Arabia almost never(although if Byzantium leads it's own war against the Arabs) collapses, even when Jerusalem is taken by the crusaders.
During the Crusades I've seen ONLY Venice redirect the crusade anywhere else(Constantinople or Cordoba), and it mostly doesn't get redirected(maybe once every two or three games).
I've haven't seen Genoa do anything but sit around and look pretty(not really, because they are often conquered by France). At least, as it seems, Venice expands into southern Italy, leaving Spain to Sardinia and North Africa.
I don't mean to sound like I'm complaining, but I'm just saying what I'm seeing with Alpha10.
Overall it's good(as some of the empires are getting at there historical peaks), but needs some tweaking(as all mods and modmods do).
