Sonic's Timeline SRB2 Message Board

First of all I'll mention I wont count spinoffs as mainline cannon games (Sonic Rush, Mobile Sonic games, Sonic Racing games) I'll count the storybooks as the gameplay has kind of a development of an early boost (although as someone who played them I must say that those boosts were crappy)
