Nintendo's website shows an extra word tacked onto this GBA title's name.
According to Nintendo's official website, Mario Pinball for Game Boy Advance has been renamed. The game is now known as Mario Pinball Land, which fits with the game's focus on moving among dozens of themed pinball boards. A single ball will often move back and forth through numerous boards, giving the game a sense of exploration that hasn't been seen since Pinball Quest on NES.
Mario Pinball (Land) was a runner-up for Best GBA Graphics in our E3 2004 Awards, thanks to its smoothly animating, colorful pre-rendered characters and boards. Look for it in North America this October.
