I will not lie, the willpower may be too much. However what I MIGHT do is take a night after Jacob goes to bed, get it setup, get at least Zoo Tycoon downloaded (that's the game he really wants), and then rebox it and wrap it so it's very ready to go when it's opened.
Or just hook it up and download the zoo game and play it
then when he wakes up say SURPRISE!!! I even have it hooked up for u!!! lol
