Need some info about single player non roman campaign

Will the romans eventaully decide to fight each other in a civil war.My selecuid empire is doing pretty good at the momment.Macedon is my biggest problem right now but the fighting 3 roman factions wont be very fun.will they take it upon themselves to kill each other?or do i got a LOOONNG fight ahead of me

Well, some people have seen it happen - whilst playing a Roman faction.

Don't recall people seeing a Roman Civil war happen whilst playing a non-Roman faction though.

So, you'd better build up for that looong war ahead of you ~:)

:balloon2:

If youre not Roman, there will be no Civil War.
