Game still treats me fine. Not as good as it was made out to be when it was fresh, but nowhere near as "bad" as a lot of people have made it out to be since. Just about every gripe about it can be explained by what year it was made; stuff like the camera and voice acting were simply products of its time.
Truthfully, the thing I hate about it the most isn't anything about the game itself; it's how it accidentally gave birth to that vocal fringe group of "Sonic can never work in 3D, it's blasphemy" lunatics.
