Dated graphics aside, this game still sizzles and pops when you play.
There are two parts of the game that I find best - one is converting the heros that come into your dungeon. Once you have a torture chamber, you can put the heros in there to convert them to the dark side. The other is possessing your creatures and being able to walk through the dungeon in a first person perspective. Now each time I see a new RTS I wonder if it will allow you to step in as one of the units.
Pros - Innovative story, terrific humor, first-person-view when you possess a creature
Cons - limited maps (can only replay so many times), dated graphics
I sincerely hope they put out Dungeon Keeper 3.
