Sonic R is a demonstration of exactly how far a vibe can carry a game. Like, as a kart racer it's horrifically imbalanced and there's barely any content at all, but despite that, I think you have to kinda' love it.

The all-vocal soundtrack is arguably the best of its kind, and the low-poly 3D models are even more stylish now than they were at the time. And bizarrely, there's not any other arcade racing game, Sonic or otherwise (as far as I know), where you run on foot? It is completely wild that this exists in the fashion that it does and the world is better for it.
