Again I love the idea but the way they set it up looks like a 8 year old picked the colors and the map needs a incredible update.
I have a copy of Superpowers, and frankly the only thing about it that I really like are the little white missile sculpts, which I use as A&A atomic bombs. (I put them horizontally in small plastic stands that I pulled from a different game.) There are just eight of them, and considering that they came as part of a whole game with lots of other sculpts (none of which I use), this reflects nicely the rarity and high cost of WWII atomic weapons.
Back around the 1980s or so, there was a WWIII-themed global game called Supremacy. It had some cool features, but it eventually faded from the scene, apparently because of two flaws: a simplistic economic model that could easily be manipulated, and a tendency to “go nuclear” that would end the game (the same kind of problem mentioned by rjpeters).
Funny. I too pretty much bought the game for parts originally and I thought of using the map for my own game idea.
