These dungeons in question should be made using basic pieces, made in Paint first and sent into one of this games art people. With that in statement I think a Fortish dungeon would go over nicely. However, in the final acception by the full staff: the player must create the icons for their dungeon, as for any doodads and what not, walls, pits, flooring, buttons, traps, they all must be drawn by the player who suggested them.
a dungeon can have many floors or even a few, as most know on this forum.
I prefer streight forwardly shaped dungeons, a classic square or circular dungeon is always nice, but we all know that nothing is ever that perfect sooo make things riggid and strange.
If any would like I could make the icon tiles for them... but... I really don't think any one should be spamming me PMs asking so please post it here.
