I've gone back and replayed Diddy Kong Racing. I think it holds up better than Mario Kart 64.
Neither of them is really playable to me nowadays to be honest, they've both aged really poorly, like most 3D games of their era to be fair.
Anyway, since MK9 is in my opinion best left for Switch 2, a Diddy Kong Racing sequel in the mean time would be awesome. I just hope they don't fall back on one of their worst habits of this gen and just remake the 64 one instead of creating an original title.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
