Nah, Zombies played better on the SNES. The SNES version looked and sounded better, and even had a secret weapon (the flamethrower).
Rock n Roll Racing also sounds way better on the SNES, thanks to the SNES soundchip which was able to replicate all kinds of different samples.
The Genesis had a faster processor than the SNES,, but the SNES soundchip was far more advanced than Sega’s. Every Genesis game had the same sound font.
Earthworm Jim 1 and and the OG Mortal Kombat were definitely better on Sega though.
The SNES version of Earthworm Jim was cropped and the game was missing an entire level. The original Mortal Kombat on SNES was big trash since it didn’t have any blood
