Paragamix did a great job with tying the storyline between all of the games.
If you are a beginner, you'll want to pick either Sherry Adventure or Adele. The answers to the questions were to be entered into the chatbot once you've found them. If you are looking for harder puzzles, Bermuda Wrecks or Carries Family would be your best bet. Secret Society Singapore had a really cool concept where you had a choice of choosing to play either the preparator or the detective right at the beginning. It's interesting to view the storyline from two different perspectives. There were definitely some cool tech uses that were designed into the 360 interfaces. If you love ARG-style games, you might find it quite fascinating to follow the breadcrumbs.
The game designers really took the players with them to places we didn't know that existed on this planet. Through the 360 image tours, we're able to enter abandoned buildings (very creepy by the way in Adele and Carries Family), explore the beautiful island of Bermuda, enter sherry cellars and roam around the busy streets of Singapore.
