- Retro Studios and Monster Games have been collaborating on Diddy Kong Racing 2.
- This is why Monster Games ported Donkey Kong Country Returns 3D and worked with Retro Studios on DKC: Tropical Freeze.
- Diddy Kong Racing 2 began as a prototype in 2006. The animal transformation vehicles idea in Excitebots (2009) came from Diddy Kong Racing 2 prototype. The animal vehicles came from the idea of riding animal buddies in the Donkey Kong Country series.
- The Wii Diddy Kong Racing was cancelled due to Donkey Kong Barrel Blasts low sales. It was also cancelled because Diddy Kong Racing DS didn’t sell as well as the original N64 game.
- Nintendo asked Monster Games to work on Pilotwings because they were impressed with the flight/airplane mechanics in Monster’s DKC Racing prototype. Diddy Kong Racing was well known for letting players ride karts, hovercrafts, and planes.
- Diddy Kong Racing 2 started up development for again (this time for Wii U) due to the amazing sales of Donkey Kong Country Returns and Mario Kart Wii.
- Kensuke Tanabe, the producer of Donkey Kong Country Returns and Tropical Freeze, pitched the idea of Dillon (from Dillon’s Rolling Western) to be one of the racers in the game. Tanabe was the producer of Dillon’s Rolling Western, and he liked the idea of having a roster of lesser known Nintendo characters.
- Tanabe thought that the concept of lesser known Nintendo characters “fighting to be Nintendo’s big star” could prove to be interesting for Diddy Kong Racing. Characters such as Mallo (Pushmo) and Rusty (Rusty’s Real Deal Baseball) were also added as racers to fill out the roster.
- Nintendo purposely held off from showing Diddy Kong Racing 2 at E3 this year to avoid sabotaging the excitement around Mario Kart 8. It sounds like Diddy Kong Racing 2 will be revealed sometime in 2015, and released that same year.
- Diddy Kong was taken out of Mario Kart 7 and 8 because of Diddy Kong Racing 2. Diddy Kong had appeared in Double Dash and Mario Kart Wii.
Okay, there's something that screams BS about this. How would Diddy Kong Racing kill the excitement of Mario Kart 8, considering Diddy Kong Racing didn't even sell as well as Mario Kart 64 (or any Mario Kart game for that matter)?
