So, Linux users aren't real people?
I'm sorry you felt my comment was rude. It was made out of confusion, not contempt.
It's just that I make games and use Linux and it's very easy to make a Linux build. Maybe with some game engines it's more difficult, but from my perspective it just feels strange to not include a Linux version of a fully released game when a Mac version is available. To properly support Mac, you have to join a $100/year developer program an jump through a bunch of hoops. Linux has none of that. To be fair, most people use Windows, so I understand why that's the main platform, but it still feels weird having Mac but not Linux, when Linux is much easier to support.
Also, admittedly, most Windows games are automatically emulated in Linux and work pretty well out of the box, but still.
You're very right that actually producing a Linux build in a lot of game engines is pretty easy. However, since the audience size is positively miniscule, and we still need to QA the linux builds at least a little bit to make sure they work properly, historically it has never been commercially sensible to do this. We still do it with lots of our games, for essentially political reasons. But it is not a sensible thing to do haha. Desire noted regardless! Thank you!
