Dude, are you for real?
Several things:
1. the Roman Empire is OVER, get over it!
2. There is no such thing as a Finnish SS division OR a place called "Kauskaus"
though there is something called the Caucasus and is a land situated between the Black Sea and the Caspian Sea, comprising of countries like Georgia, Armenia and other former SSR. In regard to your so-called Finnish SS division, it did not exist. You just imagined it! But the 5.SS-Pz.Div. "Wiking" did have about 1,000 Finns in it, as well as Romanians. So what's your ****ing point? Speaking of foreign volunteers, I have strong reasons to believe most of them were Volksdeutsche from Romania. Take for example the 7.SS-Freiw.Geb.Div. "Prinz Eugen" whose members were for most part Romanian volksdeustche. Heck, even its commander was a former Romanian general, Arthur Phelps. So again what's your ****ing point?
Finland had its own front? Whoopee doo weeee! And just what did the Finns do between late 1941 to mid 1944 apart sitting in trenches and occasionally exchanging fire with Soviet troops?
And to be honest the Romanian Army was far more independent than the other "minors". Take for example the campaign of Odessa. Name an operation conducted on the same scale by another minor with little or no German interference.
Going back to the Caucasus... German and Romanian troops have fought there longer than any of your SS Nordic Viking Wotan super ****. Heck, Romanian mountain hunters captured the most distant point in Caucasus and also the farthest advance point in Russia which was the town of Nalchik. So again, what's your ****ing point?
Don't get me wrong, I'd like to see Romania and Finland modded and honestly I don't care which is first. But when someone regurgitates the same bull **** over and over again it pisses me off.
edit:
Uhh... and what would be so dramatically different in the North? Are you saying the winters at Stalingrad were nowhere as cold and snow-heavy? or that pine trees do not grow in Southern Russia? Please tell me because I don't have a clue.
"They fought in the same battles as the Germans, for example in Arad"
Maybe, but not at squad level which is represented in RO. And like I mentioned above (see Odessa), the Romanian Army conducted operations on large scale without German troops.
