Let the adults be adults, and let the parents to their jobs. No need to grandstand on something so petty.
Good thing that such clauses are null and void in Québec, Canada.

SteamOS 3.0 should get out there for generic PCs pretty soon, in the meantime there’s Bazzite.
In that situation, Fallen Aces.
My favorite game of 2024: Selaco
EDIT: Confused by what you’re looking for, space-themed or not space-themed?
Two games I anticipated came out on Steam only, so I asked the developers if they planned to sell on alternative platforms and they did, but considering the game isn’t full done yet (they released it in Early Access) Initially I was annoyed, but after their response (they want to focus their effort on the game before adding the extra burden of managing multiple update channels) I understand why they did, on top of being a small team.
I decided to wait for one (came out on GOG on v1.0) and for the second one I decided to buy it on Steam right away since there’s still a lot of work left.
And for Linux handhelds there’s PortMaster to easily use some of them on the go.
