Do handhelds count? If so, then Tetris DS.
If not and going by time, then probably Geometry Wars or Geometry Wars 2, I play the shit out of both of those.
If going by the amount of times beaten, then probably Uncharted, but I also rarely beat games and even more rarely beat them more than once. I beat Uncharted twice and I'm pretty close to the end I believe on Crushing but some of the ways fights start are bullshit and it wasn't the trouble.
