Valve hasn’t released anything of note since this has been published. So I guess we should take these as anti patterns. Valve is more of a hat generation company than a game company so it seems like no one should take any game related advice from them.
HL Alyx and Dota 2 aren't of note?
CS:GO (remake of a remake)
Dota 2 (remake)
Artifact (flopped)
Underlords (flopped)
Alyx (good)
Counter-Strike 2 (remake of a remake of a remake)
Deadlock (early beta, but promising)
They haven't completely lost the sauce, but it's rare to see the old Valve show up these days.
