Favorite piece of Riven trivia:
If you've played the game you might remember the one spot where there's a giant sword sticking out of the ground. Since this place also appears in one of the game's FMV cutscenes they had to use a real giant sword prop for filming. The person that made the giant sword prop was Adam Savage from Mythbusters.
Cyan, by the time they got Adam's dagger prop, figured out they could do the whole thing in CG and so did not use the prop. They still thought it was cool as hell and hung it up on the wall. It was only after MythBusters started airing that they found out it was Adam's work, because he mentioned it in an interview. As shown, it now has a place of honor today in Cyan's lobby.
