Super Mario World: Super Mario Advance 2 for the Game Boy Advance, originally released as Super Mario World for the Super Nintendo Entertainment System, is one of the funnest games I've ever played on a handheld system. Sure, the Metroid games were awesome, the Pokemon games were adventuresome, the Harvest Moon games were addicting, but so far the only handheld games I can think of that are better than this game are the Wario Land games for the Game Boy Color.
Super Mario World is a 2D platformer game developed by Nintendo in 1991. The GBA re-release that I love so much was released in 2002.
The story is about the Mario Brothers, Mario and Luigi (their last name was never revealed, even though their games have been coming out for the past 29 years), and their quest to save Princess Peach from the evil . . . guy named Bowser. Well, he's more like an extra-big koopa.
Along the way, the Mario Bros. are helped by the strange supposed-to-be-dinosaur called Yoshi. Along the way they help Yoshi rescue his friends from the Kooplings, who are Bowser's children (though it's never revealed who their mother is, or if they even had one).
This game is old enough to be considered one of those games that are actually long enough, unlike present-day games. It's long enough, with eight worlds full of several levels each, and about forty-five million secrets. That's an exaggeration, but there are way too many secrets in this game. And I love it.
With several power-ups, a long enough game, and an overall super-funness, this game will occupy your time for a long time. There's no way you're going to beat in in one sitting . . . unless you know how, of course.
-A whole ton of different levels and worlds
-It's a Mario game that's not too short
-Some levels are kinda hard
-If you have a cape you can clear a lot of levels very easily
In case you're wondering, I do actually own this game. I very rarely use ROMs. Why? Because it's always 5-10 times better to play a game on the original system it was intended for. That means you could play this game on either the GBA or the SNES.
