It's odd that Wikipedia still defines 3D Blast as a main game of the series and refuses to change it. It's a spin-off; nobody is forced to talk about it when going over Sonic's history of games, it goes S3&K then Adventure, it's not part of Sonic Origins alongside other mainline Mega Drive games... You'd think they'd not want to spread misinformation with their focus on citable sources and all. Unless... Is it actually considered a mainline entry nowadays? Or is that just historical revisionism? Because no one identifies the Sega Saturn as having a mainline Sonic game and that being it after all these years. EDIT: Also, Sonic 1, 2, Chaos and even Blast were all technically console platformer instalments too, are those any different from 3D Blast?
