I think there are a lot of reasons for this, but I'm in the same boat.
- Most games tutotialize you like you have never played a game before
- "Cinematic storytelling" is everywhere. I turned off the dialogue in Need for Speed Unbound, and the game is wayyyy more enjoyable without it. And its...a racing game.
- There just are more games. Used to be I'd bring a physical copy of a game hope, and that'd be my game for a bit. Now I have thousands of games accessible at any moment. It's hard to wait for a game to "get good" when I know that.
I'd also say that I feel no need to complete games or get further into them at this point. Especially seeing how people said Starfield is best in new game plus or whatever, that game barely has legs to stand on in a first playthrough. It's not worth it for me to play a game for 60 hours for it to maybe get better, and I tend to know when I'm done with a game early now.
Valve being a private company is probably the thing that allows them to focus on putting out good products w/o dealing with shareholders demanding more.
And they make a ton of money doing right by their core consumer base, I would be very surprised if we see any of that change.
If Valve were any other company they would have laid off half their staff and coasted on that 30% from Steam. They're not perfect, but maybe the only company I feel good about giving money to, consistently.
