I recently checked my box with old game CDs and DVDs, just out of curiosity, not because I wanted to play something. Most of the stuff is just sentimental value/nostalgia, but there's one promo disc/game, I tried to archive because I found nothing about it on the net, but I couldn't even read it. Others also have read errors, but I don't know if a better drive could still work (just have a cheap external one).
I think the last PC game I bought on disc was SC2: HotS, but I don't even know if I ever used them, since you can just download the game, after you've added it to your Battle.net account. Definitely haven't used game discs since 2014, because I remember building a PC then, putting in my old drive, but then I gave it away, because I just never needed it.
