I d like to ask about 3 places of campaign map - is it an intention or mistake? I know its cosmetical detail but You know... Roman empire
1) Rhein limit - border of province is not on river, but to the west of it. Also i think there should be more cities on this Limit but what is more important different names like Germania Superior, Germania Inferior - with cities like Colonia Agrippina and Augusta Treverorum - and camps like Vetera, Bonna, Moguntiacum, Argentoratum Vindonissa instead just Bagacum (Nervicoranda) and Vesontio (Sequanilanda).
Look at original map of Barbarian Invasion (border on the north isnt visible because of player who conquered Campus Frisii north-easth from Rhein)
and look on actual RS III map
2) Danube limit - river is heading to the south in Panonia just near Carnuntum (between Panonia Superior and Inferior) instead around Aquincum (Panonia Inferior)? But province borders are correct at all.
3) region between Danube and Rhenus - Volcabrog - roman name was Agri Decumates ( boders are OK i think)
