That doesn't explain what tipped you over the edge, I honestly can't fathom your logic here. You still haven't explained how Sonic staying in the same world is a continuity mess.

Sega do indeed create games, but they also created this big Sonic world. While arguably, some odd things spring up without explanation, there are some consistencies in there. As a matter of fact, you yourself pointed them out: There's no reason to have a level in Sonic Rush with GUN mechs, nor was there any reason to mention GUN at the start of SR:ZG, but they did it anyway. Why? Because of continuity, because GUN exists and they wanted to acknowledge that, even if they have zero impact on the story.
