This is the sequel to the blockbuster adventure-puzzle game, 7th Guest. You're back in the mansion, trying to find your friend. Not only are there more fiendish puzzles to solve, but there are also riddles to unravel as well. Both will either open up more of the house, or provide further video clips, pushing the story forward. I loved the fact that I could take a break from the (sometimes insanely hard) puzzles and work on the riddles, and still progress in the game.This is a mature game--no swearing, but lots of disturbing imagery and some risque moments--nothing beyond PG-13 though. It's very similar in style to the first game, with some improvements (the sound isn't so faint, for starters), and the story is fantastic. And Stauf is as evil--and sly--as ever.
