Core Viewpoint - Valve Corporation has updated its Steam platform guidelines to restrict certain types of adult content, considering regulations from payment service providers, card networks, banks, and online service providers [1][3]. Group 1: Developer Reactions - Developers have varied responses to the new guidelines, as Steam is an open platform covering all game types with clear age ratings [3]. - The ambiguity of the term "certain types" in the new rules makes it difficult to predict the specific regulations that will be enforced [3]. Group 2: Context of the Update - The update is believed to be influenced by the controversy surrounding the adult game "No Mercy," which faced backlash for its sensitive content [5][6]. - "No Mercy," developed by Zerat Games, was criticized for themes of non-consensual behavior and was ultimately removed from the platform after public outcry and government pressure [6]. Group 3: Historical Perspective - Steam's approach to adult content has fluctuated over the years, with strict reviews prior to 2016, leading to the rejection of certain adult games [8]. - In 2018, Valve faced significant backlash when it attempted to enforce stricter regulations on adult content, resulting in a public apology and a reconsideration of its policies [11][15][17]. Group 4: Current Market Implications - The new restrictions could impact a large number of visual novels and NSFW products, which have become a significant segment on Steam, despite their relatively low median revenue [19]. - The potential for further restrictions raises concerns about the sustainability of these products on the platform, as they often operate in a precarious regulatory environment [19].
