I restricted the list to games I've played and beat. I didn't beat Advance 2 (don't plan on it, because I only got it for the chao garden).

I beat Spinball, but with save states. As for Rush, compare and contrast Sonic and Knux then Blaze and Sonic.

I beat 06, and liked it. If you put your soul into it, you can beat it. Unleashed......Dear GOD! Eggmanland alone is crazier than all the final levels in 06 put together!

As for Shadow, I focused on the fact one must beat these hard mission to pass. This can be avoided by moving left or right on the level graph, but that isn't as easy as it sounds.
