I don’t typically relay review scores or summaries here but this snippet from Game Informer’s writeup of Sonic Unleashed sums up pretty much 10 years of tragedy in one brief sentence;
Sega, if you really want to fix Sonic, the first thing you should do is stop trying to fix him.
Seriously, ditch the whole universe of forgettable characters, the vehicles, guns, swords, silly Wiimote gestures, and alternate forms. Let’s just take Sonic and make him run really fast across 300 levels per game. I don’t care if it’s 2D or 3D but I’d like to be proud of Sonic the Hedgehog again one of these days.
