These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Gameplay Derailment: The original Daytona USA let you powerslide through corners through strategic gear-shifting. Daytona USA 2 suggests that this wasn't the intended purpose of the shifter, as attempting the same technique on it will result in a spinout instead.
Make of it what you will. The HD versions have different 'trials' you can play that require you to emulate specific driving scenarios. Many of them are "drift through this turn while maintaining a certain speed" and some of them are run using a Manual transmission car. The game points out how to use downshift drifting and basically makes it a requirement (the target speeds are set higher than is doable with a braking drift if you're using a manual car).
Porting Fender Bender: The Sega Saturn port captured the fun and music from the arcade game, but not the graphics. Hardly a "disaster" but it wasn't the best effort either.
2001 had bizarrely touchy control, something brought up in nearly every review of the game. Aside from that, it nailed down every other aspect of classic Daytona, but the game is tough enough without having to battle the control.
