Well, the good part of the fanbase is overshadowed by little kids with cringy fanfiction, OCs and the Sonic Boom show is in my opinion not very well executed.
And for the good news: there are two new promising Sonic games being developed. The first is Sonic Mania, which is an oldschool 2D Sonic game with retro-style graphics. There will be a singleplayer mode, competition mode and co-op. There will also be three playable characters.
The second game in development is Sonic Forces, it has the same mechanics as Generations, and you will also be able to create your own custom character, which has a flamethrower and a grappling hook. The story takes place in a time were Eggman has already taken over the world, so it has a darker tone than previous Sonic games.
