Dungeon Keeper
The Bile Demon and the Dark Mistress

A next-generation strategy game from Bullfrog, with a twist. Build your own dungeon and strive to rid the lands above of all things nice and rosey. The familiar top-down strategy interface has been extended to allow the view to be rotated in 3D, or even better - possess a creature and play the game from a first person perspective.
