Re: Who cares
I'm dual booting between Win 7 and Mint on my gaming rig.
Probably about 95% of the time in Windows currently, but I only installed Mint a few weeks back (probably the easiest OS install I've ever done, no issues at all, and as I was dual-booting, I had to deviate from the defaults, but still no issues).
I'm also playing a lot of Vive VR games atm, which are current Win only, but Linux support is due for the Vive (HTC and Valve are not exactly MS fan boys).
I'm gradually moving things over from Windows to Mint, so far without any real issues. So I expect the % will gradually move to Mint over time.
Of the 180 or so games in my Steam library, about 75 of them run under Linux natively, including some AAA titles such as Tomb Raider (2013).
Granted I expect some publishers (especially from the likes of EA etc), might never produce Linux versions, but I don't really care too much about the mega publishers. Most of their games are just rehashed games from 10+ years ago, with way too much focus on mutiplayer (for my taste), a trend into micro-payments, and totally unimaginative, so no great loss as far as I'm concerned.
Mint just works, is easy to use, has no 'bling' unless you add it yourself, and imho nothing beats the Linux package management method of OS and software updating, rather than the complete inconsistent mess that Windows is! (Windows update, programs with their own update services running constantly in the background, automated checks for updates on launch, manually having to download and update yourself! Just horrible!).
