This. I went to check the video and there’s no way any user would expect installing steam to uninstall system packages. And yes, even though there’s errors on the screen, the average user just clicks ok so that’s the most average user experience. I do think it is strange he went to terminal to try to install when the UI failed, but as an old power user I might’ve tried the same. All in all, very unlucky for him to run into that problem, but also any normal user who immediately couldn’t install steam would just be so put off by Linux not working immediately they’d probably go back to Windows. I was also genuinely surprised the video is only 3 years old
That really sucks. Consoles these days are just pcs with expensive libraries. If you can muster playing on pc with your son, the games are cheaper and I highly recommend it. On steam, you can filter by local coop and hook up two controllers to get a similar experience. You can even try emulating older games like on the ps2.
