The controls are awful whether you're playing with buttons or stylus, so you have to really tolerate that to get to the genuinely creative core of a marketing ploy that should've been boring but was not. The DS take on 'Super Mario 64' goes so out of its way to justify its existence, with new playable characters (you don't even start as Mario – you begin as Yoshi! Ain't that a shocker), new bosses, levels, stars and secrets (and those secrets, by the way, were a big contributor of the original's excellence). I imagine that it would be difficult to plant surprises in a game that has left a legacy so iconic that every twist and turn has long since ceased to be a surprise anymore, but god, SM64 DS really does do it at points (that 'behind the mirror' star and the way the music stops? Gives me perfect creeps). The appeal of this is almost separate from the original, especially since it's definitely not as fluid or flexible a game experience either.
