Donkey Kong Racing
The game was first announced at E3 2001, with a pre-rendered trailer showing the game's concept. However, the trailer and a press release (which stated that the game was set for release in 2002) made in anticipation of Space World 2001 ended up being the only media shown to the public.
Sometime in 2002, Rare decided to only present Star Fox Adventures at E3 2002. This decision was most likely in response to a private agreement with Microsoft, who would later purchase them in 2002 just after the publication of Star Fox Adventures. Donkey Kong Racing and Rare's other titles from E3 2001 were either privately canceled, put on hold, or ported to the Xbox or Xbox 360.
After the buyout, the game was heavily reworked as Sabreman Stampede which was planned for an Xbox 360 release. However, this iteration also ended up being canceled. A Donkey Kong-themed racing game would eventually be released on the Wii in 2007, Donkey Kong Barrel Blast.
Confirmed characters in the game included Donkey Kong, Tiny Kong, Diddy Kong, Taj the Genie and Kiddy Kong (with an internal render also featuring Lanky Kong and Cranky Kong). Rideable creatures seen were Rambi, a gigantic sized Rambi, a small red Rambi, a small Rambi, Enguarde the Swordfish, a purple Enguarde, Ellie the Elephant and some Zingers. Creatures rumored to be rideable include Expresso the Ostrich, a Chomps shark, a Necky and an Army. It is unknown if all the characters from Diddy Kong Racing were going to reappear in this game, but with the inclusion of Taj, it seemed likely. It is also unknown if any other character from the Donkey Kong Country series and the Donkey Kong Land series or Donkey Kong 64 would appear.
According to the Spaceworld press release, the game would have featured the ability to "upgrade" the animal rides by collecting foods and prizes during the races. Multiplayer for up to four players was planned, as were "real world phenomenas" happening during the races, such as swaying trees and fading sunlight. The player could switch between animals during the races and it was possible for the rider to fall from its ride, forcing it to run on foot in order to catch up with the animal.
The slogan for Donkey Kong Racing is "LET'S RIDE" as it is seen at the end of the trailer.
