Touch Pad to Draw Maps

A key element of Etrian Odyseey games on the Nintendo DS is the use of the touch pad to draw your own maps. It's only really works with a touch pad, and it adds so much with the game. It's niche, not everyone will like exploring a dungeon where you draw the maps, but the touch screen is the best way I can think of making it fun. On the top, you have a first person view of what's going on.
