I never played Dungeon Keeper, but it really does play similar to Pikmin. Minions fly out spawn portals and you guide them around with the second analog stick. Attacking things like sheep for power ups, swarming enemies and picking up treasures with a certain amount of minions and carrying them pack to the portal. Red minions can pass through fire, Blue Minions can pass through water, etc. The art/story style is similar to Fable and the characters are takes-offs of Lord of the Rings characters. For example the Halfling hero has went greedy and fat and the villagers want you to go into the Hobbit style houses and take him out. The writing reminds me of Discworld, but that makes sense considering Terry Pratchett's daughter Rhianna wrote the story.
