Dungeon Keeper
There comes a time in every villains life when a choice needs to be made. Should he wander the hills ever without a home? Shall he build a mighty castle upon a high peak beyond the reach of any king's grasp? Will he live in the city, plotting and scheming in secret, ever fearful of the day when his wife finds his Necronomicon and turns him over to the White Council? Perhaps, instead, he decides to gather some local humanoids and have them dig him a dungeon. Somewhere he can assemble an elite group of underlings and train them. Somewhere safe to horde his loot and proudly display his trophies. Somewhere to keep his pets.
