Yeah, decorations of snow drifts that can appear on roads from biomes.xml would be interesting in the snow biome, so long as the frequency of them isn't too high. It might look a little odd in town, though. I don't think those can get placed on tiles, so you'd have drifts outside of town and clear roads in towns. That might make sense if there are plows going around clearing roads, but not for towns that have almost no living people (just the players and traders). Even so, I like the idea.
Of course, there could be a special set of duplicate tiles for the snow biome that have snow drift parts that have a chance of being placed on the roads if someone wanted to do something like that. Not sure how well RWG can handle a special set of tiles for a specific biome, though. It would work well in Teragon.
You could do this with sand drifts as well in the desert or even ash drifts in the burnt forest. Leaf piles in the forest. Not sure for the wasteland, though.
Anyone want to make a special biome tile pack that duplicates all the vanilla tiles into being specialized for each biome with parts for different kinds of "drifts" for each biome and also "drift" decorations for wilderness roads based on biomes? Since it's duplicating tiles and just adding parts, it probably wouldn't even be that hard to do once you have decorations to use for it. The downside is that you can't really use custom tiles in addition to that kind of biome tile pack since you wouldn't have biome versions of those additional custom tiles.
