I've spoken to a friend about this already, but a "wall world". The whole world horizon to horizon is a cliff on a 5 degree angle. It has little ledges and platforms you can walk along, trees growing through the cracks and houses and stuff built onto the side of it. The clouds go up and down, left and right. If you fall outwards, eventually you'll hit the wall further down and have to climb back up. You can follow tunnels and stuff deeper into the wall and explore all the little dwellings carved into it.
