LC should have a personal !@#$%^&*le like "Inventor of the long posts", im getting tired of reading them Well i like the idea what he said about 3D maps. Could be stored in (x, y, layer) indeed but since you (mostly) use a cube as map you will need 1024x1024x1024 tiles in total which takes a bit more memory then 1024x1024. still.. i think it would be cool to do.
