What I'm about to say might get me kicked out of the Cool Kids Club, but here goes. I love Sonic games. Not just the 2D platformers from when I was a kid. I mean, I've consistently enjoyed the series from 1991 until today. Sure, there have been missteps along the way, but I appreciate Sonic Team's efforts most of the time. Each major Sonic release is markedly different from the last, and even when it doesn't work, I respect the hell out of them for trying. It's an interesting contrast to the trends of today's game industry, where being “safe” is more important than trying new things. Sonic Team gets an idea, does it, and even if it doesn't hit, bless them for trying.
3D Sonic games have been steadily increasing in quality over the past few years. Sonic Unleashed was a thrilling, blisteringly fast game with the addition of the Boost mechanic. I remember playing that game for the first time and being blown away because it was the fastest Sonic has EVER been. On the flipside of that were the Night stages, less well received by the general public but enjoyed by a few (me plus maybe...three other people?). The night stages were basically God of War with deeper combat mechanics and better level design, but I can admit that they suffered from being too long and committing the unforgivable sin of cutting into BLARING COMBAT MUSIC every time you got into a fight.
