This one isn't like the other ones. I played the first Ravenheart and Huntsville and Prime Suspects, this tops them all. It was on sale at BFG for $2.99 so I just bought it. Every time you find all the items, you get something to help you along the rest of the game and it takes forever to finish cuz there's so many rooms to go in, so many clues to find. It's so much fun!
