1. Treasure in a Royal Tower
2. Shadow at the Water's Edge
3. The Phantom of Venice
I highly recommend each of them as they are three of the funnest games out of the series that I've played. Three secondary games include:
The Haunted Carousel
Message in a Haunted Mansion
The Curse of Blackmoor Manor
That's all for now! :) Sorry for this short first post :(.
