After playing the original Colours and Unwiished in the recent weeks, I consider Unleashed the only boost game (or at least the only one I've played, in case someone mentions Forces). Sonic Colours is a game with a boost button and some boosting segments, and I don't remember modern acts in Generations to be much different. I mean, I played the whole Colours and I was only forced to boost in a very few places (most of them to get red rings), whereas Unleashed had me constantly running, and also drifting and braking, which, in a game where you get S ranks solely by being fast, means you need to boost at every chance and keep the rings flowing to recharge the meter, rings which are more plentiful in the shortcut routes. If it's already like that in the Wii version, I imagine the HD one (which I haven't played) must be insane. While I've never been nitpicky with framerates or graphics, the responsiveness is a totally different matter, and that's also something I've noticed with Unwiished. I don't think the 50Hz PAL was the only one to blame (yes, I had to play the game that way), but the slow response or absolute absence of it at times was undeniable and any available improvement to that would have been very much appreciated. That said, the appeal SCU has for me is playing it portable, so the Switch version maybe worse but it's unique and gives what I want from it. Same for any Sonic game released on that system, really.
