While going thru my copy of Newtype USA, I came across 2 games.
Etrian Odyssey and Dungeon Maker: Hunting Ground.
Etrian Odyssey (DS) - "Etrian Odyssey is a turn-based role-playing game like any other, but it sports one heck of a mean streak to elevate it above the crowd." With this game you are respondible for the map of the dungeons with the DS touch screen.
Dungeon Maker: Hunting Ground (PSP) - "Design a dungeon so that creatures will inhabit it and you can kill them and steal their treasure. "
