I have some ideas for other users in the community to use as tilesets.
- Science Fiction spaceship or building interior
- Science Fiction city tileset
A Science Fiction theme would be intriguing for a mod.
- Modern house tileset maybe even a modern town tileset
- Grungy industrial tileset (Possible Horror Games)
- Church/Temple tileset (I feel that stain glass windows is something the game is missing)
- Original Grimrock tilesets
- Sewer tileset
