“Sonic the Hedgehog 4”
Games that have been or could be considered, in one way or another, the sequel to Sonic 3/Sonic 3 & Knuckles; official status notwithstanding.
20 Games
Intended to be the second half of Sonic 3, but you could make the case that this released as the fourth mainline game due to its standalone capability.
Not as much as the fan remake, but Knuckles does reappear…
(the 2D half of the game)
joke entry obviously, but i mean… it uses sonic 3 gameplay sprites, it introduces a new playable character and brings back all the existing ones… technically!
