I still liked it when they jumped out from behind the door. How many times was there a temple guard in that room though? There's only like 5 that I can remember: The Gordion Knot, The Keys to the Alhambra, The Blue Pearl, The Star of Sultan Saladin, and Henry VIII's Great Seal. Did I miss any?
And to stay on topic: The Room of the Golden Idols was the most pointless ever. The Treasury of Golden Orbs was actually a cool room. They should have implemented that more.
