You compete against other real players to take over the world? You’re a country and have to deal with logistics, military command, etc. It’s just a map and a bunch of info, no characters. Basically risk but more complicated. I feel like i’ve seen this but I can’t for the life of me find it.
You can do this in most Paradox Grand Strategy titles. Hearts of Iron IV for example matches your description pretty well. You have to host your own lobby though so the game won’t just set you up with opponents.
