Imagine each continuity as its own tread (games, Archie, Sonic X, Underground, Boom etc.). Everything that happens inside these continuities stay on their own threads, and thus have their own canon. Sometimes though, these threads cross over with one another momentarily (this is the crossovers) and it is at these points their continuities become relevant to each other. However, while Sonic X, Boom and Underground have crossed over with Archie's tread, the game thread remains untouched.
