Is too short, but worth the play.
The plot centers on the remote Dinosaur Planet (named "Sauria" in later games) of the Lylat System, where Fox McCloud is dispatched by General Pepper to restore the planet after pieces of it have broken off and pose a risk to the system. After arriving, Fox discovers a mystical staff from Krystal (whom Fox does not know yet, at the time) and sets off to save the planet, with the assistance of it. Fox later finds out from a Krazoa that Krystal needs Krazoa spirits to be saved.
The gameplay mechanics themselves closely mirror those of Ocarina of Time, as Fox is on foot for most of the game and pilots his Arwing only to reach another piece of the planet.
Rare was originally going to plan Star Fox Adventures for the Nintendo 64, as Dinosaur Planet, a game unrelated to the Star Fox series. The plot concerned Sabre (who later became Fox) and Krystal, along with their sidekicks Tricky and Kyte (who appears briefly at the beginning and near the end), and Randorn, a wizard who was Sabre's father and Krystal's adoptive father (who was dropped entirely). The SwapStone (which became the WarpStone) would let the player switch between Krystal and Sabre.
