I’m unsure about the game inspiration, but the movie was terrific. I love several older Russian storytellers (Tolstoy and Dostoyevsky primarily), but I never thought to give their movies a try. I stumbled upon this one and now want to check out more. It was quite good. This movie was based on a book, Roadside Picnic, by Arkady and Boris Strugatsky. This has opened a whole new world for me.
