Well there are games co-made with other studios such as Backbone Entertainment and Dimps who made Sonic games for/with Sega. Big Red button is also an example for Sonic Boom: rise of Lyric.

Plus there are handheld games based on main games that bring canon into question such as the 8-bit classics or modern games for the NDS which have stories or stages different from the games. I have my own headcanon for these reasons but as for the odd game that pushes away from canon such as Sonic Chronicles, it just leaves it to question.

For example while Sonic Chronicles had a nice story to it, the canon was questionable due to having key locations with established geology simply placed side by side for conveniance, having SWATbots and other Archie comic elements and so forth. The game itself starts off set "a few years later" after an unspecific fight with Dr. Eggman and let's not forget that Ken Penders threaten lawsuit if anything related to the game shows up again. So while I do like Sonic Chronicles for it's story I think Ken Penders made sure it is no longer canon.
