Super Mario Bros. 3
Overview
One of the very first games for the Super NES and still one of its best, this game introduces Yoshi for the first time as Mario goes another grand platform adventure to rescue the Princess...even if it's a bit on the easy side.
Review
I've been acquainted with Super Mario World for a very long time—it was one of the games at the pediatric dentist's office (even after the SNES was discarded for a Nintendo 64 later on, the square of the Item Reserve Box from SMW was still burned into the television screen), and I still pick it up every few years for a 100% run (it's not hard). While definitely one of the best Mario games and introduced a whole lot more stuff than even compared to Super Mario Bros. 3 (a jump that 2D Mario games have never seen since...indeed, in Japan the game is Super Mario World: Super Mario Bros. 4), it's an old hat to someone that has played it numerous times, so I can't rave over it like I could. But it's a comfortable old hat.
If I were to quibble about some of the smaller things that are part of the game, part of it is the theming is inconsistent. Some are named after foods (though no foods to be found), with "Donut Plains", "Vanilla Dome", or "Cheese Bridge Area", some aren't. There's the idea that it's an exotic new land, so all the enemies (besides Koopas) are redesigned or new, and that unfortunately affects the classic Goomba, too, not showing up until the fourth world and shaped like balls that don't go "squish" when you hop on them. I also didn't care about the world turning "fall"-themed with new enemy graphics after you beat the Special World (which you can do before beating Bowser).
Player Notes
This is the third version of this review. It was originally on here then received a second version that has a few errors. In the old version of this site I gave it a "GOOD" rating. (Basically 4/5).
Port & Rerelease Notes
Other being incorporated into Super Mario All-Stars as Super Mario All-Stars + Super Mario World and the various Virtual Console/Nintendo Online releases, Super Mario World has only been officially ported once. In 2002, the Game Boy Advance game Super Mario World: Super Mario Advance 2 was released. Like Super Mario Advance (the port of Super Mario Bros. 2), it adds Mario Bros....but the Game Boy Advance version of SMW isn't all that great. There are a number of changes that make the game even easier than what it is (it is not a hard game), but botches too many things, some inherent, some not so much. The screen resolution is worse, the music was butchered (including some songs being the outright wrong key, compare the real Vanilla Dome music to the butchered version. It also adds a "collect-a-thon" aspect to get all the Dragon Coins in every single level, including ones that didn't have them to begin with.

Recommended Guide
I don't remember ever using a guide for Super Mario World. Pretty sure that Nintendo published one, but the only thing you'd really need it for is figuring out where the Secret Exits are. If you don't know or can't figure it out, you can always just Google it.
