The Best Nintendo NES Game Ever: Super Mario Bros 3

World 1: Grass Land This world was the easiest of the entire game, but also one of the most fun. The game starts with Mario being able to enter World 1-1, and view the entire map and what was to come. This was a first for Super Mario games in the series. Midway through the course is a castle, where you will have your first run-in with the mini-boss Boom-Boom. At the end, you will fight your way through the first airship, battling Larry Koopa at the end.

World 2: Desert Land An area of extreme heat, palm trees, sand, and giant pyramids, Mario will jump, run, and stomp his way through an army of fire enemies, the flying angry sun, and finally to Morton Koopa Jr. on the airship.

World 3: Water Land This is where you can find the debut of the awesome Frog Suit, which will help you navigate the troubled waters much faster. Ruled by Wendy O. Koopa, this world is also home to many squid, Cheep Cheeps, and the giant fish known as Big Bertha.

World 4: Giant Land A very unique land in the game, Giant Land contains giant Koopas, Piranha Plants, and Hammer Bros that Mario needs to either defeat or sneak by. The area contains two fortresses on the island, with Iggy Koopa at the final battle on the airship.

World 5: Sky Land Sky Land is where you'll find the first appearance of Roy Koopa. This Koopaling can be found on the second half of the world. Divided into two parts, one part is on the ground, the second part being in the sky. If you do not defeat Roy on the first try, his airship can move about the world (both sections) as he pleases.

World 6: Ice Land With a total of three fortresses and slippery surfaces that make for a big challenge, Ice Land is no easy task. One of the more difficult parts of this world are the frozen plants which can thaw out and inflict damage. At the end of the world, you'll fight Lemmy Koopa, who is surprisingly easy considering how far along in the game this is.

World 7: Pipe Land With a maze of pipes for Mario to navigate through, this world contains 9 levels, 2 fortresses, and a difficult battle with the final Koopaling, Ludwig Von Koopa.

World 8: Dark Land This is the most challenging part of the game, with fire pits, Bullet Bills from every angle, cannonball shots, fast moving tanks, and pestering Rocky Wrenches. In the final battle, you will face off with Bowser in a small room. To defeat him, you'll need to allow him to jump in the air, and jump away just before he comes crashing down on top of you. The final stomp will send Bowser into the hole below.
