The Zelda community seems to be almost split in half on this topic. Many Zelda fans have called it one of the worst Zeldas ever made, while others have, even if not called it one of the best, given it almost nothing but praise. A few fans are in the middle on this, but it's very rare.
I personally say it's good, nay, great. It's one of my favorite games in history (partially because it's Zelda, so there's a little bias involved) despite the glaring flaws it has. It's one of the best games the DS has to offer imo and is a far cry from a bad Zelda game (which applies to all official Zelda games). I don't give the game a 9/10 for nothing.
But what are your thoughts on Spirit Tracks? Do you think it's good, OK, or bad? Please tell!
