RTF is a global modification that replaces all towns in the game.

When I read what you wrote, these thoughts came to mind: 1) Leave the gold mine as is. 2) Recolor the textures of the gem mine and make it crystal-like. 3) Replace the blue gems with multicolored stones (I've seen something like this somewhere). 4) Create a new gem mine using piles of stones, their textures, and some kind of lake (it will turn out to be a "lake of gems" à la Might & Magic III). 5) Take the model from this message, repaint it, and get an excellent sulfur mine to replace the original one. Well, if anyone needs it, we can move in that direction.
