None. First off, I wanna actually own my PC where with modern multiplayer titles, a shady game publisher would effectively take ownership of my PC and tell me what I can and can't run on it via rootkit DRM, if I wanna rent my hardware, I'd rather just get a console, I wanna own my PC that I built, and not give up ownership to some shady game publisher; Riot or Activision or whoever didn't build my PC, I did, and two, most multiplayer servers aren't exactly the best place to kill time in terms of hostility.

Single-player by contrast, at least for now, generally doesn't use rootkit DRM and so it can run on whatever I wanna run it on, and it's just me against an enemy AI with no one calling me -insert assortment of slurs here- because I messed up in some way or because I outmatched them.

*No, kernel-level anticheats technically aren't DRM, but they're functionally rootkit DRM, so they count to me.
