Sonic Colours for the NDS takes place in unspecific moments during the Wii version. Sonic Generation for the N3DS is like 8-bit Sonic 1, it's the same game but detour. In fact I heard that the N3DS version of Sonic Generations was originally going to consist of zones from MS/GG, Advance and DS/Portable era.

The Storybook series is definately canon as in Sonic Generations he recalls how the adventure is "no stranger than rescuing genies from magic books"

Known Sonic comics and cartoons have their own canon and lore seperate from the games. Yes Archie sometimes make Sonic comics set In Another Time, In Another Place which are more canon close than the comics themselves.
