You can tell a videogame is good when you find yourself playing it in bed. Not on a handheld, but in your head. When you close your eyes at night and all you can see is falling blocks or twinkling jewels, you know you're on to a winner.
Super Monkey Ball: Step & Roll is not much good at all. It's barely playable, in some regards. In others it's moderately entertaining, but it never reaches the heights of the classic Monkey Balls - the ones which were all about precision control, fiendish level design and funky mini-games. So how come I see it in my head at night?
Because what I see isn't endless ramps and big bananas and sweeping blue skies. I see a nightmarish vision of Aiai, dancing. Instead of a t-shirt he sports a stained velvet waistcoat. His trademark quiff is trapped beneath a brocade pillbox hat. His fur is matted and patchy, his eyes glazed and soulless. And yet he keeps on dancing, while a giant blue hedgehog with a razor-sharp grip turns the handle on the organ.
