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.
