Super Mario Bros.

Super Mario Bros. was released for the NES in 1985. Universally considered a classic of the medium, Super Mario Bros. was one of the first side-scrolling platform games of its kind, introducing players to huge, bright, expansive worlds that changed the way video games were created. Super Mario Bros. is one of the best-selling games (possibly the best-selling game, depending on estimates) of all time, and was largely responsible for the initial success of the Famicom and Nintendo Entertainment System. It has inspired countless imitators (eventually founding an entire genre) and was one of Shigeru Miyamoto's most influential early successes. It also brought Mario, who would later go on to become Nintendo's mascot and more recognizable among American children than Mickey Mouse, to prominence. Shigeru Miyamoto described his initial idea for Super Mario Bros. as "a character that bounces around. And the background should be a clear, blue sky.

The player takes the role of Mario, or in the case of a second player, Mario's brother Luigi. The ultimate object is to race through The Mushroom Kingdom, evade or eliminate King Koopa/King Bowser's forces, and save the Princess/Princess Toadstool.

Mario's primary attack is simply jumping on top of his enemies, which kills the mushroom traitors, known as Kuribou/Goombas, and sends the turtle soldiers known as Nokonoko/Koopa Troopas into their shells. Mario can then kick these shells into other enemies, which will conveniently dispatch them; but conversely, kicked shells can bounce back off of walls or other vertical obstructions and hit him. Jumping on enough enemies in succession, or kicking a shell into enough enemies in succession (combos), results in double points earned with each enemy killed, eventually earning Mario a 1-up, an extra life and another chance to pass the level.

Aiding him in his quest are several power-ups, including the Super Mushroom, which would turn Mario into Super Mario, doubling his size; the Fire Flower, which turns Super Mario into Fiery Mario, allowing him to throw fireballs; Starman, which gives him temporary invincibility; and the 1-up Mushroom.

Mario can be hurt if he touches an enemy. If he takes a hit from an enemy as Super Mario or Fiery Mario, he simply reverts back to regular Mario and the game continues. However, if he takes a hit as regular Mario, falls down a pit (regardless of status), or if the time clock runs out, he loses a life, and starts again. The point where Mario continues depends on how far he ran through the level before dying; either from the very beginning, or at one of several invisible "checkpoints" throughout the level. The game consists of eight worlds with four levels in each. Though each world is substantially different, there are basic similarities: typically the first sub-world is a generic above-ground (overworld) level, the second is in an underground dungeon or underwater (or in the overworld with a unique challenge), the third is a series of platforms suspended high in the sky, and the fourth is a fortress or castle. At the end of each castle level, Mario fights "Bowser" (who, until the final level, is actually a lesser enemy disguised as Bowser) across a bridge over a pool of lava. In the later worlds, Bowser throws hammers as well as occasional fire breaths. Bowser may be defeated in one of two ways; either by touching the axe at the edge of the bridge (thereby dropping Bowser into the lava), or, as Fiery Mario, throwing fireballs at him to defeat him directly.

The third and sixth worlds take place at night, and all other worlds take place during the day.

After beating the game, the player is given the option to start the game again in "'Hard' Mode," where all Goombas are replaced by Buzzy Beetles (Koopa Troopa-like enemies who cannot be killed by fireballs), and all enemies walk faster. In addition, some of the elevator-style lifts are about 60% their original size.
