Second sentence:

If that isn't replay value, what is? How often do you replay Single Player games _with_ replay value then?
I played Final Fantasy VII Remake twice, because they made the game so you can’t get everything by going though just once and I also wanted to get the PS trophies. So I replayed it, though I found it tedious and annoying at times. I don’t remember how many hours I spent but certainly under one hundred.
I’ve replayed all these games, but I wouldn’t say the latter has replay value.
I've played Alyx once and fully intend to play it again with developer commentary. Valve's commentary mode is always a treat. But beyond that I don't see myself coming back to it often. Just like with Portal.
On the other hand, I have played through Half-Life 2 quite a few times. Of course, there are also open world games like Breath of the Wild or Skyrim where I have many hundred hours of time spent.
Most of the user base doesn't get sick from smooth locomotion though. Maybe teleport was better back when the project started in 2016, but in Q1 2020 especially after boneworks which came out in Q4 2019 people would see Alyx as dated. Smooth locomotion wasn't even in the game from a Q4 2019 build of the game. Continuous turning didn't even make it in until after the game was released.
Now I can handle smooth locomotion, but at the time it'd make my stomach lurch.
