It just didn't "click".
Super Mario 64 DS will bring you to a great 3D Mario environment, with 4 different playable characters, and plenty of stars to get. Though I must say, after getting through the excitement of buying this new game, getting stars seemed more like a chore, instead of sitting down and having fun. If you've played Super Mario on the N64, I see nothing here that would interest you, unless you would insist on playing it through once again.
Graphics:
A little more bright, and Mario looks a tad better, but otherwise there's nothing new here.
Sound:
Sound is good, and the music is appealing.
Value:
Not worth the $30. The game turns into a chore instead of having fun, and if you've played the game before, you won't be missing out on anything if you pass this one up.
To sum it up, it's a fair game, controls felt a little odd, and it gets a little old, real fast. I couldn't recommend it.
