although not as good as the original, it is still a great game in its own right and a nice addition to the ds library.
there are several differences in level design(mostly to accomodate for the new characters) and the controls arent nearly as precise, but it is still a great game. the graphics are a step above 64 but it doesnt quite show us what the ds is capable of, the new characters are fun but often times make the game easier than it should be (Im talking to you luigi!), but it still retains many classic moment and the min games are a welcome addition(though multiplayer loses its zest after a while).
though not the classic I was hoping for, it is still a good game and deserves a play through for any mario fan, just dont expect the same thrills, if you want that you might as well dust off the N64 and play the REAL tick tock clock.
