There's something about the Ratchet and Clank series for Sony's family of PlayStation consoles that keeps me playing "just one more level" to find the next special item, upgrade, or mission when I really should go do something more productive, such as eat or sleep.  The folks over at GameFAQs.com must know of this addictive experience as well considering how the site truncates the title of the latest game, Ratchet and Clank: A Crack in Time, on the list of the top ten currently popular games in the site's PlayStation 3 division.  When I think of all the possible ways to weed down the list of potential abbreviated titles, I realize there must be a method to their madness after all.  Now if you'll excuse me, I'm off to play more Crack in the den.  There's just something about this game that won't let me quit.
