The distance maintenance is calculated by distance from cap/max possible distance between cities. For a given amount of tiles (a x*y map), the max distance in a flat map is (x²+y²)^1/2, on a cylindrical map it's ((x/2)²+y²)^1/2 and on a toroidal map it's ((x/2)²+(y/2)²)^1/2. Or maybe they use a different distance than the usual one. Anyway, the max possible distance on a toroid is smaller, therefore the distance maintenance is bigger. I could use one of the sandboxes to test out what the maintenance will approximately be.
Civic maintenance also depends on map size, but org will help with that.
The two major techs to keep the economy running are currency and CoL (and maybe MC if we don't ban the Colossus). Especially on this map with a lot of inter-continental trade routes. The idea will be to get to currency ASAP (gettting a second 2c TR in all cities will be a nice boost and we can then build wealth to help fund research). Then maybe CoL early to get our half priced courthouses. Of course getting a high commerce tile in line before that will help, but it won't be enough.
