How quickly does a game have to hook you before you put it away?

It depends on game length. For exmaple, FFXIII is suppose to take 40 hours to beat so I will let the game take a few hours to get going. Gameplay-wise, FFXIII is quite boring for the first two hours since all you can do in battles is attack. It gets much better after that when the system gets more depth
