So the Razor and blades model (printers) but in games?

Get in a shop and look at the samples there. For me, i can’t tell the difference between 30 and 60 fps, despite having 120% with glasses.
Btw, cinema effect (24 fps) is slightly over the conscious limit of 25 fps aka 40ms window. And TV series are fine with 30 fps. But the optical chain is in large parts independent and the optical effect that a still background light (vs CRT strobe on dark) doubles the required fps (70 to 100), so it can’t be said for certain. Observation in a forum told me, that fps-sensibility is trained to a certain degree, with tasks/games where you follow the mouse or movements with your eyes (me a creative builder and programmer, rather than a competitive gamer or designer/CADler). But who knows.

Not on games per se but almost on mods. Yes, there are other platforms, but the majory and newest are on Workshop. And they make it hard to download them, if you don’t own the game on Steam (and Valve has it in their terms that they own the mods hosted on Workshop).
So one could argue that they use the indirect peer-pressure approach to market dominance, similiar to Google on Android.
I wouldn’t complain if they just had a “Download” button on their web version. But they don’t, you have to use the finicky steamcmd intended for server administration.
With some tool that uses a hack. Just plopping doesn’t work anymore.
RAM eating we browser? What, you playing games on 256 MB?
What, you only play games on a powerful rig? Waay more Casual games in the store than Flagships. And if your notebook has 4 GB and Steam uses 1 GB and you want to lookup a tutorial online it gets close.
Let’s not normalize wasting resources just because some AAA studios are used to it.
Ah, Steam proton. They could just point the
drive_c/users/steamuser/<dir>symlinks to $XDG_DATA_HOME instead. But considering that the “use XDG dirs” issue is unanswered for years now…
