Nightmare Mode discusses the difference between the value of a video game and its price, and how arbitrary pricing of games and DLC force us to treat games as products rather than an art form.
"We expect our games to have legs. There’s an implicit value to our games that has nothing to do with mere price. It’s the reason I can pick up Bastion for $15 and see it as an absolute steal, and at the same time pick up Street Fighter IV on my iPhone and feel like I overpaid.
The value games have is experiential, and has nothing to do with the price of the physical game itself. When we buy games, we’re not excited about the cartridge or disc, rather we’re excited for the hours we know we’re going to spend with the game."
