Unlimited Adventures allows players to create their own fantasy role-playing games, especially those set in the Forgotten Realms world. The basic elements of each created game (i.e. design) are its modules, that is, the levels that the player will be traveling through. The designer builds the modules by arranging walls and choosing floors and ceilings. The game comes with a lot of art, depicting various monsters, characters, items, etc. You can also import your own art. (mobygames.com)
