There's a brilliant meta-game feature in Noby Noby Boy, which compiles every player's "progress" in the game and uses it to propel a single "GIRL" across the solar system. But her progress is danger.
See, it relies on lots of players playing lots of Noby Noby Boy for those cumulative figures to get her anywhere. And while first-week sales saw the player base reach around 60,000, which got her from Earth to the moon in only four days, there's now only around 1000-2000 people playing the game.
Which means that, at the current rate, it'll take her over 2000 days just to reach Mars. We could extrapolate that and work out how long it'd take her to reach, say, Uranus, but that would be both childish and depressing.
If creator Keita Takahashi built this feature into the game to guilt us into playing it more, well...congratulations, Keita, you sick bastard, it's working.
