Love playing this scenario as it offers so many strategies and options for the player. And i love to have multiple factions on the map than just standing fighting against one ex. Parthia.
But isn´t the scenario a bit short? 25 turns to manage your corner of the Roman Empire, with all the rebellions popping up. Batavian Rebellion, Revolt in Britain, Jewish Uprising and so on.
I think a 35-50 turn would be more suitable, i often feel a bit stressed when knowing the turns are ticking away. It makes me think that the scenario just goes out for the first man to conquer Rome wins :S
