By “basic ideas” I mean with regards to maps, units, research, diplomacy, UI, things like that.
I have never played Europe At War, so I don’t know much more about that game than what can be read on the website and forum and in screen shots.
Reading between my lines – I’m trying to decide if purchasing Europe At War would be a good thing before or after purchasing The Great War. And since I’m deep in to Panzer Corps, afterwards might be best.
