I started gaming at weird time tbh, the Snes was already out and a few friends had them so I honestly do not know which game was really my first dive into the hobby, it was Either Super Mario Bros. Or Mega-Man X.
My parents got me an NES when I was 6 (which was 1993 fyi) and a box of a bunch misc. NES titles of which SMB 3 was the most played as the rest were either bad games or didn't work half the time.
