Valve has already sent support for the new Steam Controller upstream: https://www.phoronix.com/news/New-Steam-Controller-SDL
Which is also one of the reasons so few new things get done, and why they (until now) haven't been able to count to 3.
To get anything done you either have to be able to do it entirely by yourself which is unlikely, or get enough others organized and on board to make it happen.
What? Valve released CS2 like last year? They do stuff all the time. They have like three games they're actively maintaining while making HL3 and three new pieces of tech? This is a wild, unfounded take and feels ideologically bound.
That was 2023, and one of very few things made not to specifically promote their hardware or as a cheap spinoff of existing IP. And define "actively maintaining", because general bug fixes for decade old multi-player games and managing item marketplaces doesn't require much manpower.
Going further back there's Aperture Desk Job which was a tech demo for the Steam Deck in 2022. Then an extended cut version of Artifact originally meant as a sequel in 2021, which is a Dota 2 card game, but still remains unfinished, so effectively abandoned. Then Half Life: Alyx in 2020 which 90% of gamers can't play because it's VR only, and clearly made to further promote their VR hardware. Dota Warlords in 2020 which was originally a community game mode. The original Artifact in 2018, which had abandoned iOS and Android ports. The Lab in 2016 which was made to promote the launch of the HTC Vive. A zombie CS spinoff in 2014, Dota 2 in 2013, CS:Go in 2012, Portal 2 in 2011, and Left 4 Dead 2 in 2009.
If you remove the spinoff and niche stuff from the list you get game releases in 2023, 2020 (arguable since it's VR only and thus inherently niche), 2013, 2012, 2011, 2009.
That's a pretty big gap of not much for the last decade game-wise. Its been previously documented and published that Valve has issues getting games developed because of the flat organization structure. Articles like this.
You are also missing the huge advances they've made in their contributions to FOSS, like proton, FEX, arch, etc. Steam has done an insane amount of legwork to get Linux gaming off the ground. They are the one company that made migrating off of Windows and onto Linux a valid option for me, and a bunch of other folks. Linux was ~0.89% of their userbase in 2020, and since their contributions to these FOSS projects, it has gone up to 3.05%. That's crazy, considering it had been at or below that 0.89% since 2016.
Deadlock too, open release of TF2, Dota2 has continual updates with exceptional depth that calling surface level/maintenance/spin-off is baseless for, active development to stop cheating across its catalog, compatibility with ever evolving gpu tech... They're not a game development studio first, I could concede that based on revenue. However they're not slacking or demonstrably 'not getting things done.'
