I remember when me and my friend had a setup for VF5FS at Defend The North 2015. Asked Dbomb and Rendering star if they wanted to play and they said, "Na, I'm good" The one time we could've. *Sigh*
Because its Sega. If its anything other than Sonic or Yakuza, then they ain't going to bother with it. Like, literally, one of their best games as of late, Sonic Mania, was developed by the ones who make/made fanmade Sonic games (which actually was a decent choice, because they're doing some great stuff) and the ROM hacking community.
