I'm looking for a particular genre of video game, but I'm not sure if it's ever been made.
What I'd like is a WWII strategy sim (turn based, probably) where you can either the Axis or the Allies against each other basically from the get-go. It wouldn't follow historical battles, but rather each game would play out differently based on the outcomes of each battle previously. Sort of like a "choose your own adventure" WWII strategy game. It would be fun to see if you could play as the Nazis and actually fight off the Allies, or play as Japan and try to broker a deal with Russia to move them to your side, etc.
Maybe I'm crazy to even think that a game like this exists, but I think it would be fun.
It could even be a series of games. WWI, etc.
