I've been playing forever on M/M-- with a few games on H/M, where there didn't seem to be much difference. But, just for giggles, I played my first game on VH/M as Julii and was stunned! Within about 10 years or so Spain actually sailed TWO armies to Italy (simultaneously) and attacked me!! The unmitigated GAUL (sic) of 'em. Nothing remotely like it had ever happened before. Ok, I still won, but it sure put a crimp in my plans. So, notwithstanding possible economy & diplomacy cheats, I think I'll stick to the VH campaign mode where there is at least a possibility of something different happening.
