Well what about Sonic adventure wasn't that the only time a 3D sonic game worked with the Sonic stages as a genuine platformer?
Sure, but we’ve come a long way from Sonic Adventure at this point. Sonic plays completely differently now. I don’t know if it’s as easy as saying “just do SA1 again” because they’ve already been there, done that, and moved on. I would be viewed as taking a step back, which isn’t something many game companies like doing.
This is actually part of a larger problem in the industry and is one of the leading reasons we get Kickstarters for games like Bloodstained, A Hat In Time, and 90’s Arcade Racer. Some developers are so obsessed with finding the next evolution of their genre they lose sight of what’s right in front of them, leading to someone coming back around 10 or 15 years later and saying “what if we just did a new, good version of these old ideas?”
But, for what it’s worth, I like the boost gameplay really lots and I want more games in that style, as long as they do it right.
