As originally reported by Kotaku, Steam has finally implemented an “LGBTQ+” tag for games on its platform after developers and players drew enough attention to the issue.
Steam’s game discoverability and recommendation algorithm is largely determined by their tag system. If you go to the page for, say, Shadow of the Tomb Raider, you’ll see tags like “Adventure,” “Lara Croft,” or “Female Protagonist.” Mouse over one of these and you’ll get taken to a hub page of sorts that shows you other similarly defined games. Historically, it’s been difficult for smaller studios to get their game noticed among the sea of possible choices, especially if their tags didn’t align with certain genres. Steam users have been able to make custom tags for a few years now, but Steam doesn’t use any of those for its algorithms, so they’re effectively useless. On top of all that, Steam removed custom tags from its hub functionality, essentially leaving developers who custom-tagged their own games as “LGBTQ+” in the dark.
