Sorry, Windows won the monopoly war. Linux is too complicated and mostly not supported, mobile is too small to play correctly and lacks periferals, and Mac lmao
Well for starter i really like what valve have been doing with steamos,making linux more user-friendly. But yes,windows is still ahead in term of larger compatibility and easy to use
Windows, hands down. Gaming on Linux is a meme and the less is said about Mac, the better.
For mobile obvoiusly Android, in iOS it's an absolute pain in the ass to do anything in the files system at all from what I've heard.
I use windows but if you live in Australia you should use Linux because their government think even if it's pixelated and fictional it will still count as **.
