20. On April 1, 2011, Valve’s Potato Fool’s Day alternate reality game began with codes showing up in thirteen indie games that were collected in the “Potato Sack Bundle” and offered to Steam users at a 75 percent discount. Including titles like Super Meat Boy, Bit. Trip Beat, Audiosurf, and Amnesia: The Dark Descent, the Potato Sack bundle incentivized purchasing and playing the games to accelerate the release of the much-anticipated Portal 2 (2011). By building a metaverse between multiple titles, Valve not only flattens a series of otherwise separate indie games into a single, monolithic genre, but also flattens alternate reality games to the pages of their online storefront, Steam.
