Because of the very good questions of Glycerius i would liek some suggestions about the objectives of the several factions.
For the byzantines i thought it would be good these objectives:
-defeat their greatest enemies: The Seldjuk turks
-defeat armenian rebels (cilician armenia) and conquer Antioch (these things have been done by Ioannes II Comnenus and by his son Manuel I Comnenus)
-take Damietta in Egypt, some lands near Jerusalem and some lands in southern Italy( Manuel I sent an expedition in southern Italy and after that in Egypt leaded by Stephanos Contostephanos).
What do you think? and write what objectives would be good for the other factions.
