There’s now a way for Steam users to signal their interest in a game being available for their preferred platform.
Valve has made a change to the developer side of Steam that gives developers a breakdown of the different platforms people choose when adding a game to their wishlist.
This is helpful because it also shows platforms that the game does not currently support, letting the developer know how much interest there is for ports on platforms other than Windows. This is obviously only limited to PC operating systems, so Mac, Linux, and SteamOS.
If a Steam user has a single preferred platform in their personalised store preferences, every game they wishlist – regardless of whether or not it’s available on that platform – will be sent to each respective developer.
For instance, if a Steam user only plays on Mac, and they’ve set their store preferences to only show Mac games, Steam will notify the developer of every game they wishlist that doesn’t have a Mac version. This brings no change for users, but it’s one way you could push for a Mac or Linux port of your favourite game.
