I like your idea for an overworld, has some potential. Maybe there's one dungeon entrance, with a randomly generated dungeon, but with the artifact for the dungeon being brought back for a reward, like, say, a wand with 15 charges, repeatable daily with a different reward each time, but you can still enter the dungeon for loot. Four different areas, 3 availible immediately, and the last one leading to a final fight with the lich, with the orb. City ruins: Houses lots of goblins and the sewers for a dungeon. Hillside cave: Like the current cave floors, but with 3 floors, all random each time. Cultist catacombs: Catacombs below the town, relatively easy, populated with zombies, wizards, druids, and theives. Final shrine: Once all dungeons have been completed once, the shrine opens, with one floor, the lich, and the orb, similar to the current final floor.
