Well, obviously piracy if you’re into that. Apart from that, using cheats for games, dumping your physical games and having a permanent copy you can use without the CD and an active license (probably possible with a digital game too I assume? not sure), applying patches like a 60fps patch for Bloodborne, emulation of PS1, PS2, PSP and a bunch of other consoles etc etc.

Running Linux if you’re that kind of person :P
