My comments apply to PI and China only. Not to the present one, genius.
Why only script two seasons? Did you not like the outcome of those seasons. Oh, too bad. So sorry. *sad face*

If they scripted those seasons, they would have made them a lot different. Rupert would have won PI, and China would have gotten rid of the boring people first. They probably would have scripted PG to win too since she's Chinese and all.

Face it, the reasons those seasons turned out the way they did is because the producers don't have complete control over the game. Although there are probably times when they wish they did.
