One of the best SNES games comes to the Wii Virtual console
This game isn't for everyone, though. If you get tired of being in the same area, or you don't know where to go or what to do, the game slows down almost to a stop. Backtracking is a necessity, and you'll be going through the same parts at least two times during the game. It's worthwhile to write notes on a notepad of what you found and correlate it to your map, so you don't forget to get whatever it was you know you left behind.
I found it good enough to play again in the Virtual console; I hope that if you've played it, you'll feel the same way. If you haven't played it, but like exploration games, I believe it's a must-have in your collection.
