Steam's new 'anything goes' policy is doomed from the start, reckons Tyler. Valve's decision to no longer police games on Steam—except for those that are illegal, constitute "trolling," or fail to meet technical quality standards—is a contentious one, which the publisher spent 1,000 words attempting to explain yesterday. 

As Tyler posits, implementing this will be difficult. As reported by VG24/7, game designer Brenda Romero supports Valve's "open platform", as she perceives it, and that as a creator she wants access "to the full range of the human experience" when making a game.
