I imagine that a lot of people would retroactively pay $100 (i.e. future-you would be able to easily convince past-you that paying $100 is worth it). I wonder what mechanisms exist for capitalizing on that retroactive price. You can obviously make the up-front price higher, but this obviously erects a barrier to people experiencing the retroactive value. Some other ones that come to mind: paid DLC, "remastered" versions released N years later (Skyrim has famously done this. I think I've paid for 3 or 4 $60 versions of Skyrim at this point), and open "tip" jars / patreon style support. Any other ideas?
