Here you go!
These are old tiles made by myself and Spram... and maybe others! (I know one's by Luna, and I forget where a few came from and I wanted to wait until these all were) They are in the public domain, although aren't widle used right now. They will eventually be used in newer versions of Sully so people can have actually good public domain tiles.
Just give credit to the original tile authors in your credits and readme if you use them.
All of the pcx's in the main directory show off the tilesets in the folders with the same names (0003-0.PCX shows off the vsp in the ./grue0003/ folder, ruins-2.PCX shows off the VSP in the ./ruins/ folder, etc etc...)
Check out, in specific, the Spramnew tileset. Offhand that might be what you're looking for in a town set.
Hope that helps!
