Nintendo's streak with the original Super Mario games is just stupefying. Following up on the absolutely fantastic Super Mario Bros. 3, Super Mario World entered the 16-bit era with guns blazing. An utter tour de force of level design, visuals, music, and sound design come together to create the greatest platformer to have released by 1990 and still one of the best of all time. I can't heap enough superlatives on this game. It took that ability to constantly reinvent which Nintendo had mastered in the previous games and just spit out level after level of engrossing gameplay.
