Sonic the Hedgehog

Super Mario World or Sonic the Hedgehog? Super Mario World came out in North America on this day in 1991. Sonic had been out since June. My aunt would come over on the weekends every once in a while and bring her Genesis with her. That's how I played Sonic, and I played it well before I ever played Super Mario World. We didn't get an SNES until around 1993. Super Mario World was in the box and me and my mom played it nonstop. I like the original Sonic games but Super Mario World is one of the greatest games ever made. Which one was the better 16-bit game?
