I’ve been dual booting Ubuntu and Windows for a good few years now. I keep the windows around for gaming, because, ahem, I don’t like giving EA, among others, money. I know it’s not a problem to play most of the games I’ve paid for on Linux, but does anyone have experience with playing games on Linux that you’ve, somehow, obtained for free? And keeping them updated, too?

I’m still going to dual boot because keeping my games separate from my work is a decent adhd strategy for me, so I’m open to gaming friendly OS suggestions as well!
