We've wanted Marvel vs. Capcom back for years, and the newly revealed Marvel Tokon: Fighting Souls looks like it will scratch that itch. But Arc System Works was too slow as dedicated Sonic the Hedgehog fans have raced onto the scene with a marvel of their own.
It's fair to call Sonic the Hedgehog the series with the most prolific fan-game community of all time, considering fan games from Christian Whitehead got that guy hired to make official ports and then eventually lead a team in making Sonic Mania – an official mainline Sonic game and the most beloved series entry in years. Meanwhile Sonic Robo Blast 2 is a well-loved release that's been in various stages of development for over 25 years at this point.
