I kind of have to disagree about Sky Chase Zone, it's a welcome change of pace (especially after Metropolis Zone), and I used to think it was really cool as a kid. The idea of being up in the sky was a cool gimmick and I loved flying past Wing Fortress and having that small amount of environmental story telling. I'll agree that it's kind of boring for me to play through now, but I have been playing the game for 20 odd years. I'll agree that the Lava Reef Zone boss isn't great though. It's both boring because you can just jump for a few minutes and beat it, whilst being unfairly unforgiving if you slightly mess up. I agree with the comments about the characters thematically, but ultimately it would have meant some major work to incorporate massively different play-styles into Sonic 3, as ultimately the levels don't allow for it. I remember for a while as a kid wondering why anyone would play as Sonic when Tails or Knuckles had all their special moves, but now I've mastered the insta-shield and the item shields, Sonic is far more fun to play. If done properly, it would be really awesome to have Sonic be Sonic, Tails be Sonic on easy mode due to his swimming, flying, flying tails attack, but no super form or full ending, and then Knuckles have a very different, slower play-style based around punching and exploration. Realistically this would have risked far too much money because everyone would have said "ugh why the fuck am I going slow in a Sonic game!?" anyway. I think something that I would have liked to have seen addressed in a theoretical re-release of S3K would be some Tails specific paths in the S&K sections, because in S&Ks often more confined levels, he's underutilised at best, and game-breaking at worst. I've never felt much of a problem with the general idea of the (classic) ring mechanic, as it allows more freedom to enjoy one of the main selling points of the ability to go fast, and allows for the difficulty to be scaled quite nicely with more hazards, non-killable hazards such as pits, crushers and water and less rings to rely on, as the game progresses. One criticism I would offer would be that most of the bosses don't use any of the skills that you would pick up in the actual gameplay, and become a test of getting to the boss and memorising the pattern rather than a test of your skills at the game. This is especially true of the end game, where you're put in an unfamiliar situation with no rings whatsoever. Other than that, things that are bullshit: The timer should reset after you beat the boss on Death Egg act 2 in S&K (or just can the boss because it's boring, requires little skill and takes too fucking long). The spinning pole things sending me the wrong way in Wacky Workbench only serve to annoy. Pretty much everything in Metropolis being an unfair dick move. The bugs features in Metallic Madness 3 are just bullshit. Sonic games are good though, really. You should play them some time.
