latched onto the game, and it was decided N-Space and Nintendo would work closely together to develop the game. After six months, object possession was introduced in the game after some suggestions from Shigeru Miyamoto. Geist was first shown to the public at the E3 2003 and it was later stated that Geist would be released the same year. In the months after the E3, both companies realized they "weren't working on the same game"; N-Space had envisioned Geist to be a first-person shooter while Nintendo (more specifically, Kensuke Tanabe) considered it to be a first-person action-adventure. The adjustments caused the game to be delayed many times until it was finally released two years later in 2005, but Geist was present at both the E3 2004 and E3 2005. Nearing the end of development, a Nintendo DS port was rumored by an IGN tour to be in development. Although this port was never announced, and no information of it has ever been officially released, n-Space did have development kits for the DS at the time, and traces of the port's existence have been found within the ROM of the DS version of Call of Duty 4: Modern Warfare, which was developed by n-Space, as two text documents for the credits of "Geist DS" are present. The Geist franchise is currently owned by Nintendo, due to their contract with n-Space. Reception Geist was Nintendo's E3 2003 surprise announcement, as it was not a new title from one of their staple franchises and no rumors about it had been going around before the E3 2003. In general, people were enthusiastic about the demo. Two years later, the game received “mixed and average" reviews according to the review aggregator website Metacritic. While the game was praised for its originality in ideas, gameplay, and story, it was held back by a weak engine (IGN: "Unfortunately, a game engine incapable of matching n-Space's ambitions occasionally hampers the experience.") which meant Geist was unable to maintain a smooth frame rate throughout the first-person shooter sequences. The game suffered from sluggish shooter controls that were not on par with other first-person shooters of its time. Nintendo World Report wrote: "There's a constant struggle with the controls that makes the game more frustrating than it should be," and IGN called it "not exactly poor, but it certainly doesn't compare to better shooters on the market, either."
