That's useful and ontopic, but the thing I'm frustrated about is how difficult it is to track if you or your opponent are close to getting supremacy midgame. You have to go far beyond counting number of icons, like in empire, suddenly it matters which color is supplying the icons, and there's 5 different sets of four colors you could use, and 6 different icon types that could reach supremacy, and it's just nuts to keep up with.
But, I mean, if I achieve this in age 1 or 2 when feasible I'll have to deal with that less often, so thanks.
