I think it is pointless to worry about people pirating what you create. It is going to happen regardless. The people that are going to buy it will buy it. They people that pirate it would not have bought it in the first place.
With software you can put some basic protection on it but DVDs and CDs are easy marks. You just waste energy worrying about something you can't control.
The Hateful Eight, Star Wars TFA, and The Revenant all showed up on torrent sites before they were released in theaters. My kids were watching Star Wars TFA at school when another student had a copy on their phone and were showing to everyone a week before it opened.
This film has the benefit that most people have no idea what an Amiga is let alone want to pirate a movie about it. As I said, the people who are going to buy it will.
