So, I've tried creating several maps with the cheat mode, and several things occured to me:
-Iron is way, way too rare. Actually, sometimes I'll generate a decent map with iron being just decently rare. But 1 or 2 iron nodes on a large map (yes, it happens) - and sometimes 0 on a medium map!!! - isn't fun. Metal is a much needed resource, not something optional like crystal, and needs to be more abundant or 3/4th of the tech tree becomes useless. Evey side in a game needs to find at least one iron resource pretty quickly; the challenge then not being to have access to iron, but to have access to a lot of iron for heavy armors and weapons.
-Sometimes, resource distribution is totally nonsensical. I sometimes find 3 refugee camps on 3 adjacent tiles. I don't think it's just random (what are the odds), but rather a generation algorithm in dire need of a lot of work.
