Super Mario Bros. on the SNES.
Funny part was after watching for so long people actually playing the original Mario Bros, especially 3, I was psyched and asked my parents to buy a NES to get me to do it. They managed to get me......the SNES, which I was a little young still and unsure what it was, but it didn't look the same so I felt a little disappointed by the idea..until I finally discovered that it was the newly made system with new technology.
But yes, Super Mario Bros rocked

. Although I will admit that everyone gives me funny looks whenever I told them that yes, I managed to go through the 'entire' game, and didn't go through any of the teleporters n.n;; Silly, yes?
