I'm finally moving myself and my parents over to Linux this weekend. I'm putting them on Mint and I think I'll probably be using Debian 12.
For the longest time it was games that prevented me from moving, but with what MS has been doing as of late, and especially with them trying to force copilot/recall onto systems/my Win 11 install refusing to get security updates anymore, I went and checked my entire game library on steam against the proton db and found the following.
95 of my games run natively on Linux. 31 of my games are rated platinum. 73 of my games are rated gold. 12 are rated silver. 3 are rated as bronze. 3 are unplayable.
This shocked me a little when I counted it out as this is a huge improvement compared to a few years ago.
The actual difficulties I will be facing are getting all of my music/sound production stuff functioning well enough to use.
But yes, anyone who claims they won't move to Linux due to gaming in the contemporary is either sorely out of the loop or hard stuck silver in a game like Valorant which they cannot bring themselves to drop and artificially refuses to run on anything where it can't have kernel level anti-cheat.
