I was reading Surprised by Joy for the first time yesterday, and this struck me:
Lewis says (speaking about him and his brother in there childhood):

"We never saw a beautiful building nor imagined that a building could be beautiful."

Now that is patently false for anyone born in the 1800's in europe. Ugly architecture, like florescent lights, and atomic bombs, wasn't invinted untill the 20th century! Living in 20th century America I would say that he never saw an ugly building nor imagined that a building could be so butt-ugly.

Also this:

"I am the product of long corridors, empty sunlit rooms, upstairs indoor silences, attics explored in solitude, distant noises of gurgling cisterns and pipes, and the noise of wind under tiles. Also, of endless books."

That pretty much somes up why I love myst, riven and adventure games in general. It's fitting that the brothers miller were Lewis fans.
