ROFL. Despite video games, starting with the NES, being my whole world until the age of 13 (and still a significant part of my world until, I don't know, age 19 maybe?), I have always sucked at video games.
I've never even beaten the original Super Mario Bros. Even when I revisited it as an adult. Even on Super Mario All-Stars where I can have a save point to world 8-1.
