just a thought

I was just watching the first Twilight Princess trailer and had a sudden thought. if you havent seen it it says "But as the light fades, will the hero rise again or will darkness reign". What if Twilight Princess is a game like Shadow the Hedgehog or Fable where you make choices that affect the games story and conclusion. Its probably just in there to sound cool but its a possibility right? this would help fill the 100 hours theres supposed to be. its doubtfull but you never know.

well I don't think Nintendo would ever let Link be evil and i'm very glad too, it would make no sense whatsoever.

However, it might be possible that they put in some sort of failure senario. whereby instead of just redoing certain missions there is an alternate outcome to particular quests, so that you can make different journeys through your quest each time you play.

If that was the case it would vastly boost the potential gametime, because there would be mutliple routes through the game and this would explain the 100 hour game time idea thats been floating around.
