Super Mario Bros. invented 2-D platforming as we know it. It started it all and revolutionized gaming forever.
Super Mario Bros. 2 (USA) was an awesome game with many new features, but in a way more of a diagonal step (just a little forward, and a little sideways) from Super Mario Bros. While still an amazing game, people remember it more as an experiment on the side or "not a real Mario game" or something, because it wasn't the gigantic revolution people expected after SMB1. It was still incredible, but people expected more.
Super Mario Bros. 3 was a magical heaven, mastering 2-D platforming. It added a ridiculous amount of powerups, and a ridiculous amount of completely different worlds and level designs, and even introduced some minor multiplayer parts. And it introduced flight.
Super Mario World took all the magic from SMB3 and improved on it. It added crazy new things like Yoshi, switch palaces, Mode 7 magic, multiple exits per level and thus multiple routes through the map, the Star Road, Special World, ghost houses, the ability to turn into a balloon, but at the expense of removing several items (the music box, the hammer, the warp whistle), several powerups (frog suit, racoon suit, tanooki suit, Hammer Bros. suit, Kuribo's shoe, P-Wings), the multiplayer part, the airships, the ability to fight the sun, the sky tower, giant world, pipe world, etc. Super Mario World was many steps forward, many steps backward, many steps sideways, and just all over the place, and at least as insane as SMB3.
Super Mario 64 invented 3-D platforming as we know it. It started it all and revolutionized gaming forever.
Super Mario Sunshine was an awesome game with many new features, but in a way more of a diagonal step (just a little forward, and a little sideways) from Super Mario 64. While still an amazing game, people remember it more as an experiment on the side or "not a real Mario game" or something, because it wasn't the gigantic revolution people expected after SM64. It was still incredible, but people expected more.
Super Mario Galaxy was a magical heaven, mastering 3-D platforming. It added a ridiculous amount of powerups, and a ridiculous amount of completely different worlds and level designs, and even introduced some minor multiplayer parts. And it introduced spherical worlds (and countless other shapes) with multiple centers of gravity per level.
The next Mario game will be the Super Mario World of 3-D platforming.
