Super Mario Land (series)

The Super Mario Land series is a sub-series in the Super Mario franchise for the original Game Boy. This series, unlike the previous Mario titles, wasn't worked on by Shigeru Miyamoto, but his mentor, Gunpei Yokoi instead. It lasted from 1989 to 1993. Starting with the third installment, Super Mario Land 3, the series turned its focus over to Wario and ended up spawning the Wario Land series.

Super Mario Land
Super Mario Land was the first game in the series, released in 1989 for the Game Boy. This game also marks the debut appearances of Princess Daisy and Tatanga. This game possessed many similarities to Super Mario Bros. for the Nintendo Entertainment System. As far as gameplay is concerned, it had the same basic gameplay style as the others. The player would make Mario run, jump, collect coins and power-ups (including the new Superball item), kill enemies, go down Warp Pipes (which usually contained underground areas with coins, just like Super Mario Bros), etc. The boss battles were also very similar, where the player either had to avoid a boss' attacks, run underneath them and hit the switch behind them, or just simply shoot them until they're destroyed. Super Mario Land also featured a new gameplay gimmick, in which Mario would have to steer a submarine in an underwater stage, as well as piloting an airplane during the final stage, where Mario has his "final" showdown with Tatanga to rescue Princess Daisy, whom he kidnapped, supposedly in an attempt to get her to become his queen so that he could rule over Sarasaland.

Super Mario Land 2: 6 Golden Coins
Super Mario Land 2: 6 Golden Coins was the second installment in the Super Mario Land series, released in 1992, three years after its predecessor. This game marks the debut appearance of Wario, Mario's arch-rival. In this game, it was revealed that the events that took place in Super Mario Land were merely a diversion created by Wario so that he could take over Mario's castle. He also used the power of six magical coins to seal the castle, and left them guarded by nine of his followers (including Tatanga) so that Mario cannot get inside. Now, Mario must travel through five different worlds to obtain those coins and get his castle back from the greedy anti-hero. Notable aspects of Super Mario Land 2 are its improved graphics, as well as a save feature, which wasn't present in its predecessor. Just like the last game, however, it kept the same traditional Mario-style gameplay, and even brought back the Fire Flower power-up. There's also a new power-up, which is a carrot that will allow Mario to glide across certain areas. Like Super Mario World, Mario now has the spin jump ability, which could be used to kill certain enemies instantly.

Wario Land: Super Mario Land 3
Taking place after his defeat in Super Mario Land 2, Wario decided to go on a quest to earn himself enough money and riches to get himself a castle of his own. During his quest, he finds many treasures as he battles Captain Syrup and her army, the Black Sugar Pirates. The gameplay in Wario Land was slightly different from the previous Super Mario Land installments. For example, if the player holds down the B button, then Wario does not run. His speed does increase, however, if Wario is using the Jet Wario power-up, which allows him to temporarily fly through the air at super speed. His other power-ups include Bull Wario, which gives him super strength and the ability to stick to ceilings and conveyor belts, and the Dragon Wario power-up, which allows him to breathe fire. Wario is also able to hold and throw enemies (as well as coins, which are usually required to exit a stage).
