Yeah, i find this game to be far more enjoyable than it's sequels and the Rush games. The Rush duology and Advance 3 bored me to sleep and Advance 2 pissed me because of it's extreme automation and poor trial and error based level design.
This is the closest Sonic has ever come in this day and age to capturing the essence and fun of Classic Sonic.
Oh, and Pinball Party was okay but it was just a no frills cash in pinball title with some cool Sega character appearances and remixes-it may as well have been called "Sega Pinball Party." It did have a nice sense of style, and i love the Nights pinball table.
