Not quite a simulation. You can make alliances and truces and such, but you need to be attached to the countries involved. The countries just sort of exist, there's no simulation as to why. So basically you're just observing a bunch of countries you don't know getting into wars for no reason. Mods don't help it much as of yet.

I guess it's fun if you have a map you already drew up and want to simulate that.

8 bucks for this aint worth it, should be free. or 2$ at most

Fun to "play". Generate a new map and take bets on who will survive. Feeling naughty? No problem, nudge your favorite nation to supremacy or cripple your enemies.
