@coolboymew There are people that just want Sonic and Tails to run fast to the right, beat up Dr. Robotnik, get the chaos emeralds and save the animals
There are people that like the dozen or so characters that the Dreamcast games had and whatever weird lore they slapped together on top of the shift to 3D
There are even people that embrace the cringe the post-Dreamcast games had
It's not one fandom, it's two or three, and you kind of have to choose who you're catering to. The sidescroller fans want a Genesis game. That's it. There's no need to "seek a new audience," just use it to give millennials memberberries and if the games are good, then it will attract others that are curious.

But like @Indigo said, we're talking about Sega, they're fucking retarded
