I was wondering if anyone else has done any attempts at altering the world gen parameters beyond the in-game alterable limits, and doing things like setting river generation to 2000, or max altitude to 700? (Not recommended btw, nearly nowhere to embark)
Here's a list of what I've done.
[DIM:513:513] didn't do anything, it was kept at 257*257
I've set the variance to 25600:25600 for some options. Setting them to 51200:51200 kept giving me "Mountain region count fails by ~50ish", but I couldn't figure out how to lower the non-rejection limit.
Setting the max and min altitude weights to 15:1:5:1:15 seemed to help a bit with this, but I'm uncertain.
I also set max subregions to 128000, as I kept getting rejects. There's also the issue that it seems only civ's with [START_BIOME:MOUNTAIN] can embark due to mountains EVERYWHERE, but editing the entity file fixed that.
Peaks and Volcanoes seem to have a negligible effect on the above rejection, I've set them to 0, and to +500 and the map reject log still gives approximately the same rejection amounts.
I've increased cave size to 500 with no apparent problems.
Cave amounts I'm still playing around with, but I've seen no apparent problems with setting them to the 2-3000 range
Setting erosion cycle count to over 2000 leaves you without steep cliffs. (I was trying to maximize the odds of creating deep river canyons) This also seems to effect the number of mountain reject counts, but it's quite minimal. Ie, going from 400-2000 make the mean number of too few mountain regions change from -40ish to -45ish, but the variance changed from +-10 of the mean to +30-15. More analysis is required.
Civ number was bumped to 150, and pop to 30k just for the hell of it, no apparent problems.

Note. On a core i7 at 2.3GHz, map generation can take upwards of two hours, with the majority of it spent on a rejection just starting 'Running rivers' (the mountain reject), and on Importing wildlife. (due to the stupid number of biomes I think)
Any thoughts on how I can further increase huge river canyons, up the chaoticness of the map, and reduce the small number of lakes that form?
