I like flexible terrain that could serve for a variety of adventures. Thus Cave and Sewer would get my votes!
Also would suggest a mega carrying case that holds several sets...
- Sewer Setting
- Abandoned Temple
- Prison Setting
- Cave Setting
Drawf,Temple, and Drow
The cave theme would probably be the most different looking compared to the first project -- so this would be my vote. The variety would show people the full range of options your terrain system can handle.
Some of the other themes seem like they could be smaller expansion sets that build upon some common base sets.
- Sewers and prison could be expansions to Dungeon base set.
- Volcano and crystal/mushroom caverns could be expansions to Cave base set.
Cave, please :-)
Dwarf and drow
I would gladly buy every single one. Make them all please. 😅
In order, top to bottom: Dwarf, Temple, Cave.
I'd go for a cave setting.
Abandoned Dwarf volcano temple. :)
Tough choices; in order I would probably buy:
