- Some kind of realistic, unexotic forest tileset with trees, animals, ponds maybe.. (most nature tilesets are more towards the exotic end)
- Modern luxury ship? Like, a boat. Not space ship.
- Volcanic. Not hell, but including outside areas with craters, geysers..
- Lava temple. There are a few tilesets resembling this, but no tileset really seems to have this as a theme as far as I can remember (although something like this exists in most games).
- Military - tanks, turrets, rifles, bunkers, etc (turrets that fire at Jazz?)
