Well, I will probably make a smaller one specifically for MP use after I finish my SP 800 province map for myself. Like I said, I paid no attention whatsoever to balance for the 212 map, just figuring out how GIMP works. I never said it was good for anything specific.
The 800 province map I am building for myself and those who enjoy massive all ages SP player games ... if this is not you, sorry. If only 3 people see it, well I suppose at least one of them will be the only person which it matters to me
Also, for those who don't recognize the terrain, it's a false color satellite image of mars, with oceans placed at the -3ish km mark. There really is no "terrain" drawn to speak of (ie, no forest or mountain icons). Most of the provinces were drawn more or less according to topographical and geographical maps, but without any other real forethought.
The larger version is going to be much more well thought out with a wide range of diverse terrains and interesting encounters, which in the end will be balanced for SP play.
