why not? i might give it a try. if i do change this willit affect maps i have already generated and started playing?
Just new worlds you generate. If you want to delete the saves and world from the user and game folders, you can regenerate the same seed at different water levels until you get something you like. Just exit out of the game, edit the file/save, delete the world and any saves you created and then go back in between each world regen.

Why are there deserts next to Snow Biomes?
Shouldn't there be a mini-biome buffer in between or something?
You can play with the biome ranges in the RWG xml file mentioned for water level changes. I have got a pattern now that usually has them separated, although sometimes with some seeds it cannot be avoided without totally removing all desert or snow biomes. In those cases I find a different seed.
