Interslicery

Tried to join the community multiple times (including accepting requests), and it just won't let me in. Whenever I think it is, it backs me out to the home screen and I'm not in it. So... I dunno. Whatever..
I doubt they'd trust the insert-disk authentication thing, that was the primary attempted PC anti-piracy measure (known as Securom) for aeons and it was always trivially easy to circumvent for end-users, once the haxors did their work (the no-CD cracks).
IDK if anti-piracy is still an active feature of modern games TBF, a lot of games are just always-online things nowadays where even if there are people that can be arsed enough to try and replace that server, there's still a sense of missing out if you play on the illegal / private servers. Steam definitely helped a lot, I think.
Also you wouldn't be able to install no-CD cracks on the PS4 anyway XD
Also PC plays all the older generation games, even console games,
I've seen PS3/360 .iso files floating around on the torrents, though. Huh.
PS2 Classics and PS2-formatted disks not compatible with PS4
