Long speech, short message: Fall of Rome is Vanilla Bi how it should be, and Invasio Barborum really feels much more different. Both mods are great. It depends on whether you like a vanilla like gameplay (like ROP) or a new experience (like in Europa Barbarorum, the greatest mod ever about the post Alexandrian Antique).
