I’ve always been a huge fan of Bullfrog’s Dungeon Keeper. And while the official sequel was a failure, we’ve always got Dungeon Defender to fall back on.
Dungeon Defender quite obviously draws its roots from Dungeon Keeper. You play the overlord of a dungeon, which you can dig out using imps minions. You can use gold to build various monster lairs, which essentially function as monster generators, like in Gauntlet. And you can build traps. Wonderful, beautiful traps.
