Compared the other Mario Advance games, this one doesn't bring all that much new to the table. It's still a good game because, come on, it's freaking Super Mario World. A few nice bonuses are added, like Luigi having his slightly different physics. But the port itself is definitely the most skippable of the Mario Advance quartet.

Of course, when I was a kid with a GBA who didn't have access to the SNES, I sure didn't care. It was still a very good Mario game.
