Maybe not "stopped" but at least fell out of the public eye for quite a bit of time. It's really something that I haven't seen brought up since like... Free Riders maybe. Though then again... that was the last time they were relevant wasn't it?
Real talk, I know how Sega gets with this sort of shit and I feel like they're close to bringing back these characters in a playable state.
i just want tails playable in a 3D game again damn it, these people need to stfu XD
