This is an interesting take, especially coming from a non-gaming focused tech website like Ars Technica. I feel like it’s been too long since people were truly hyped about half life 3 though, and this wouldn’t be enough, even if Valve did go through with it.
People are increasingly unhappy with windows though, and the EoL of windows 10 may push people to Linux anyways.
It’s more than enough to make HL3 a Steam exclusive. And make it run well on the Deck. If Valve really wants to gild the lily, they could put a little side-story just for the Deck’s controls. A follow-up to Aperture Desk Job, perhaps.
