Sonic 3 & Knuckles Playthrough FinaleThis is it. This is the end of Sonic's game. These next boss battles involve the fight with what would be the final boss for Sonic if the 7 Chaos/Super Emeralds weren't collected (as in, you had to have all 7 of either; no mix between the two) and the true final boss at the Doomsday Zone.
I might do Knuckles' game one of these days since his game, though shorter, is different from Sonic and Tails'.
But, for now, I'm gonna record myself playing through every stage of Super Mario Bros. 3, as I've said in the first video's description. Not at this exact moment, of course, because I need to take a short break...
