Back in 2017, Valve rolled out a small change to the wishlist feature on Steam that quite a few people still don't know about.
We previously posted about this when the change happened but as always, things get lost and people forget. If you head to this page (click your username -> Preferences) on Steam when you're logged in, scroll to the bottom and you will see this:
The box above doesn't mention it, but this allows developers to see wishlists from a single ticked platform. Why is it important? Well, we speak to a huge amount of game developers and a very common issue we've come across since this was implemented was a very low volume of wishlists from Linux.
A lot lower than you would expect, some of which is naturally due to our lower market share (of course) but also because so many people just don't know this feature even exists. We've also ended up reminding a lot of our readers and followers on this, with a surprising amount of people having no idea it's even a thing.
Since it's a manual process (and only works if you tick just one platform), if you don't go and do it yourself your wishlist entries on Steam don't show up as being for Linux. So it's a feature that sounds good on paper and is well meaning but doesn't work that great in practice.
