So a friend is going to gift me one game if I do some stuff for him, and I am thinking of getting winSPWW2 or winSPMBT. I don't mind the historical period as I like both, so what I am looking for is variety in the scenarios and the units.

I have a general knowledge of WW2 armament, and I've seen that MBT game has 93 nations, but if it's based on modern times a lot of nations will share equipment right? Because a lot of nations nowadays do share it. Also, I don't know which kind of environments are displayed on the games, and I am looking for more urban focused environments so if you can tell me which ones are more varied (WW2 or MBT) and which one of them has more urban areas?

Sorry if this request is stupid and obvious, but I don't know much about war in general and I don't know much history aside from the lessons at school when I was 14-16 years old and the little to no coverage in news channels
