This is more how I would see a post-apocalyptic RPG I would run shaping up. There are no bands of marauders riding across the desert, nor are there any Gamma World mutants. Nature is beginning to re-assert itself over the ruins of civilization, but people are still wearing 'normal' clothing rather than running around in leather with mohawks, and technology still exists - see the start of the video with the laptop.
Red Markets, with its concept of a separation between a post-apocalyptic wasteland with the survivors of a highly developed society, works quite well. There is still a part of the world that has protected itself from the disaster, and continues to do so. Its agents may still operate in the wasteland, pursuing its own agendas. Readers of the Amtrak Wars series of books by Patrick Tilley will recall how the existence of the Amtrak Federation is a major plot point. Similarly Kass Morgan's The 100 trilogy, features two such technologically advanced societies battling for supremacy.
In the Alan Walker video I quite like the concept of the lone figure equipped with advanced technology adventuring through a wasted landscape, seeking a house in an old photograph. It raises many questions that could form the basis for an RPG scenario - why is he looking for the house, what does it hold, how is he able to get his laptop to work, who sent him?
Red Markets has now raised over $50,000 and is well on its way to becoming a colour hardcover book. Check it out here.
