Super Mario Brothers was released for the Nintendo Family System in 1984 as a sequel to Mario Bros. which was a game Shigero Miyomoto made while working for Nintendo during college. It's story is told if you wait on the title screen and it revolves around the titular protagonist, Super Mario, and his often forgotten brother Luigi, going through nine worlds to save his girlfriend Princess Peach from the clutches of an evil king named King Kooper who is a big fire breathing dragon. There are bricks in the game which you can smash to get a powerup, like a mushroom that makes Mario turn older or lets him shoot magic fire balls that kill the enemies after a few hits. The enemies include small brown things, but also there are turtles, beetles, spiky beetles, and a man from the clouds who drops spiky beetles on your head, and sometimes magic fire balls are a hazard. The levels are sometimes repeated because Miyamoto said they didn't have enough space on the game cartridge, but it's okay because there are over 40 levels, and you can beat the game again, so that's actually 80 levels. If you hold the A button on the controller, Mario will run, and if you press the start button, it lets you look ahead in the level to see the obstacles. A rumor is that there are special pipes in the game (Mario is a construction man) which you can use to visit another world for a few seconds, but that was an unintended glitch that got patched out of the American version of the game. Super Mario Brothers ended up with two sequels, one where Mario has to go through 130 different levels and defeat a bird named Birdo, and another one where his friend Toad and his girlfriend Peach are there and he goes in a shoe at one point. The shoe had super powers and so Nintendo decided the shoe cannot be in any other games. That is what "Nintendoheads" call the Mario Mandate, and it is also why the mushroom in Super Mario 1 is orange while now it is red, or why Mario's hair is orange while now it is brown.
