Oh dimps Sonic.
[spoiler]
Advance 1 was great, a true Sonic 4. Special Stages were a pile of ass though.
Advance 2, overrated as [parasitic bomb], hated the special stages, Amy wasn't NEARLY as good as a character that she was in 1, the running bosses were dumb, and Pits everywhere!
Advance 3 I like because of the Chaotix mechanic. The special stages were fun too.
Pinball Party is an okay pinball game but story mode's too tough.
Battle's pretty fun, that's all I've got to say about that.
Rush 1 is okay, but [tornado fang] Altitude Limit.
Never played Rush Adventure or Colors DS. Or Generations/Lost World 3DS for that matter.
Unleashed for Wii is boring and too werehog heavy, its not even fun werehog stuff like the 360/PS3 version.
Sonic 4 is terribly mediocre, its not a good Sonic 4.
The music for the most part is great though, that never really changes with Sonic.

But i've said this many times before.
Sonic Boom just looks strange in general, I see it more as a Crash game in Sonic skin more than anything else.
