I am going to buy a new nancy drew game and don't know which to buy. I'm thinking of one of these four: Shadow Ranch, Warnings at Waverly Academy, Trail of the Twister, and Castle Malloy. I really like scary ones with a good plot and fun activities. I've played a lot of them and so far my fav's are the royal tower, blackamoor manor, and the crystal skull. any help? thanks :)
