I was just 3 when I played on a Sega Genesis for the first time. Sonic 2 was the greatest thing I’d ever seen. Lewis Hilsenteger (aka Unbox Therapy) gave a similar opportunity to his 4-year old and he did infinitely better than I would have at his age or today.
The game in question was Streets of Rage, another classic and you can see how he did below.
UPDATE: Unfortunately, the video was taken down. Instead, watch this 11-year-old play on a SNES and a Genesis for the first time.
