I would argue that many people are sick of constantly seeing "groundbreaking" as a way to freshen up the series. What many would agree is the pinnacle of the series, Sonic 3 and Knuckles, is the end result of iterative research, development, and enhancements. Not groundbreaking game, not putting in a new style of gameplay. Just simple old iterative refinement. Many game series's (And, incidentally, most projects - both entertainment and not) suffer from attempts to break from an iterative approach, and revolutionize itself to become better. It often falls flat on it's face. The Sonic series is nothing more than an extremely good example of this problem in effect. I hope SEGA allow the Mania team to keep their iterative, evolutionary development up, hopefully, for further game projects. Goodness knows being revolutionary has been nothing but bad for the series. In both reputation and quality of projects. EDIT: For a quick and lazy example of a series where an evolutionary/iterative approach has largely been beneficial, over a series of decades, take a look at the evolution of the 2D Mario platformers. Even with the largeish gap from the end of the SNES era, and the beginning of New Super Mario Bros.
