Geist review. Classic Game Room presents a CGRundertow review of Geist for Gamecube. Geist does many things against the norm. First it is a FPS that mixes things up with new elements. Also it's one of the few Nintendo published games to receive a Mature rating. You play the game as the disembodied soul of the main character. You must search through the complex to find your body, stop an evil corporation and prevent an ancient evil. You do this by possessing things in the world, either enemies, animals, or objects. As a straight FPS it is a little underwhelming, but with all the new elements, it makes for an entertaining experience. This video review features video gameplay footage of Geist for Gamecube and audio commentary from Classic Game Room's Ryan.
