Sonic the Hedgehog

Because the original game isn't bad on a conceptual level, it's just dragged down but being buggy as shit.

The game's not awful, it's just broken. The ridiculous quantity and length of load screens was obviously avoidable. Levels try a lot of things that work fine most of the time, but suffer hilarious bugs for no sane reason. There were surely unaddressed playtester notes about how annoying certain bosses were - both for gameplay, and for repetitive audio barks.

I dunno that it needs a full from-scratch remaster, but it could definitely stand some professional updates. Or drop the assets into a new engine so it can take fresh shaders and feel like it's copying Mario Odyssey instead of Mario Sunshine.
