Sonic Rumors - Sonic Generations 2 found on Roger Craig Smith's IMDb Site
IMDb is a website that has information about games and movies even ones that are not released. Anyone can edit and make pages on IMDb. In late 2015 someone made a page for a fake game called "Sonic Generations 2". It had false information about the non-existent game. It even had voice actors listed. The page has not been archived but Roger Craig Smith's IMDb page which had listed Sonic Generations 2 is archived.[1]
