- there should be enough space for dynamic models, of course really huge miniatures like dragons still doesn't fit in my dungeon... that would be really too difficult to build
- there should be visible squares on the floor, I want to use my dungeon as playground for both boardgames like Mage Knight Dunegon and fantasy wargames like Mordheim
- the dungeon should be modular, I want to make different rooms and arrange them as I wish (part of the fun is building the dungeon!) and I also want to be able to expand the dungeon
- you should be able to combine the tiles as you wish without considering given sequences of tiles (i.e. the external wall of one tile can become the internal wall for another one)
- base tile 3 x 5 squares
- long wall
- short wall
- corner
- fillers
- door arc (lots of boardgames uses some kind of doors!)
