Diddy Kong Racing got a remake for the original DS a few years ago and left fans of the original mostly unsatisfied. Some of the original characters -- specifically the ones that, after the N64 version of the game, became original RareWare IPs -- were replaced with some of Diddy's monkey friends. That, along with various gameplay changes, made it a very different game from the original.
This is one of those games I remember specifically going to a friend's house to play. The variety of game types and vehicle types made it different than Mario Kart, and it'd be awesome to have that back and recreated on the Switch!
