The Byzantines should, by all accounts, be one of the weaker factions. Their military was outdated, their position weak, they were suffering repercussions from the lunatic Diogenes and also the invasions of Guiscard, which had circumstantially resulted in Alexios draining his treasury to tie up the Normans.

The Seljuqs should be powerful, as should the French, I think.

Egypt was too problematic, after Shahanshah died, the place disintegrated for a while.
