Reason for this meme is that some ubisoft titles are shipped with a broken version of ubisoft connect launcher. Installing these games is only possible by running the installer for the launcher again via protontricks.
and therefore is the one and only acceptable proprietary launcher.
Yep!
But that's only until they decide to enshitify, which they (Valve) will, because they (the humans making the correct choices today) will sell or retire.
I've been running a hacked-together script which uses a disembodied copy of Proton 8 (aka. copied to a portable drive, doesn't need to have Steam installed to run) to launch my games from Itch and GoG.
Hmm, just tried to use Proton 9.0-2 and the current experimental in my steamapps (which appears to be version 9.0-202), and it works just fine. Though, I guess Lutris' implementations are quite a bit more advanced than my hacks (no debugging let's goooo).
A very simplified version of my script, for those who might be interested: pastebin.com/kbNNvzAx. Don't forget to uncomment game_exe and set it to your executable - won't work otherwise.
Steam has an effective monopoly on open, marketplace-style launchers. EGS is their only real competitor and everyone hates it. GOG is years behind the curve and Amazon's launcher barely exists. At this point in time, Steam is hardly considered third-party since it's so ubiquitous.
Some people hate it, including some independent developers. I wouldn't mind going without it, if there was a Free Software library management alternative. I want something to track what I have installed (because I've "lost" things and reinstalled them before) and something that has a decent uninstall.
I also get some benefit from the store integration, but I can understand developers being annoyed at the 30% "steam tax". I'd gladly purchase using some other method, if I didn't have to sacrifice library functions from previous paragraph.
