Valve’s new refund policy has two main stipulations: you have to have purchased a game less than 14 days prior, and you can only have played it for two hours or less. The latter, especially, has people up in arms for a number of reasons.
The system, some people worry, seems highly exploitable. For some games—say, The Witcher 3 or GTA V or Clicker Heroes (why can’t I stoppppp)—two hours is just a drop in the bucket. But for others—smaller, more personal games along the lines of Proteus, Gone Home, and Papo & Yo or even bigger budget experiences like Metal Gear Solid V: Ground Zeroes and Portal—two hours can basically be the entire thing. So, in theory, someone could buy one of those games, play it to completion (or close enough), and then get a refund. Boom, free video game. For obvious reasons, that could hurt game creators pretty badly.
