'ey mayne I ain't tryna be rude but that was with good reason. We've all done weird shit that made no sense in the past, and turning South America into a supernation was your weird moment.
Hmm, I'm slightly confused. Does each character control an entire nation, along with provincial tribes/officials/noble families, or is there a different player for each region?
The Roman Empire began to disintegrate in the early 5th century as Germanic migrations and invasions overwhelmed the capacity of the Empire to assimilate the migrants and fight off the invaders. The Romans were successful in fighting off all invaders, most famously Attila the Hun, though the Empire had assimilated so many Germanic peoples of dubious loyalty to Rome that the Empire started to dismember itself.
Like others have said, it's the most interesting of the bunch if only because I get to march in formation with big red shields and shout in Latin.
