For the U.S. sequel to Super Mario Bros., Nintendo retrofitted an Arabian-themed Japanese game called Yumekojo Doki Doki Panic with the familiar Mario clan. Other than a few minor graphical changes, the two games are nearly identical.
With the Mushroom Kingdom safe for the time being, Mario and his crew seek out new adventures in Sub-Con. A dream world taken over by the demented Wart. This sequel is missing the two-player feature of the original. But adds the ability to choose from four playable characters at the beginning of each level. Mario, Luigi, the Princess, and Toadstool. Super Mario Bros 2.
Rather than jumping on enemies to defeat them, Super Mario Bros. 2’s primary attack method involves picking up items and throwing them. Vegetables can be plucked from the grass and thrown, but other enemies will also work. Certain areas, a magic potion will emerge from the grass instead of a vegetable.
Each playable character has a complex interaction between their speed, strength, and jumping ability. To put it simply, Mario is average in each category, Luigi can jump the highest, the Princess can float but is otherwise weak, and Toad can’t jump well but is the strongest. Super Mario Bros 2.
Although it was originally based on a non-Mario game, many of the items, enemies, and gameplay concepts introduced in Super Mario Bros. 2 went on to play an integral role in future Mario adventures.
