I used these first two hours working out the QR codes and starting on the database. Since the base game does not have an expansion code, it made sense to start with that. I got about halfway through making a CSV containing the card ID (which is encoded in the QR code as well as written on both sides), author, title and release year of each song in tue base game. My end goal is to write an iOS app, and I am already thinking about how to distribute these databases. Do I include them in the bundle, or do I load them from a web site?
