Okay...
1. As for layered creature images, with subcell rendering available, it now seems like a more obtainable goal. For now I'm not worried about working on it, but in the future...
2. Resolution - I'm going to work on tossing together a proper 'Game Settings' section for settings like these, along with various worldgen tweaks (water/land ratio, etc etc). Because of my work schedule and life in general I'm not going to project a definite time frame to have this done, but it shouldn't take *that* long.
3. Repetitive civ names - Civ/history generation is currently in its infancy. I had to put it on hold because I need to tie in a lot of information from as-of-yet-unfinished segments of worldgen (Creatures, Gods, etc) before being able to proceed - this is because civs will have their various symbols/icons, legends, histories, and whatnot all tied in with other worldgen elements. Some civs might be founded directly at the whim of the gods (either by raising a previously non-sentient race to sentience, or by providing some kind of technology a la Sid Meier's Civilization, or whatever). Civ-gen/history will also need Creatures and Spirits to be finished because they will all depend heavily on being able to tie elements from each in to their legends and culture for thematic purposes.
4. Yeah, civs should spread over water. I'll work on that. Shouldn't be too hard.
5. Peninsulas getting named like islands - this might be really hard to fix. It shouldn't have too much bearing on things in the long run, although I'll look into correcting it. But the island-finding/lake-finding algorithms work this way in order to avoid slowing even high-powered computers to a crawl - they basically work on a 'almost always correct... most of the time' logic. The result is an occasional oddity or misnamed feature.
6. Dark mountains - I could try tweaking these. I personally prefer the color the way it is, though. But now that I think of it, I might just have to allow users to tweak world color schemes to their own liking via the Game Settings tab. Anybody else think mountains should be lighter?
7. The finished worldgen soundtrack rocks. I'll include it in the next tech demo along with the other changes. Thanks, Sentientdeth!
