I’d also like to add that the yakuza series used for this picture are great games that now come with DRM, unless you buy them on GOG.
I bought a big bundle of the games through steam on sale and Yakuza: Like a Dragon came with DRM on steam. Buy on GOG, its the same game but DRM free.
I should have waited for the GOG sale, now I might pirate it to play the game I bought without DRM.
Well for games it kind of depends on the specific DRM used and how exactly the game utilities it. DRM means digital rights management but there is a wide variety of DRM and ways it’s used.
Some DRM might limit the amount of computers software can be installed on, some might verify the contents to ensure none of the files were changed, some might authenticate with a server before starting up, and some might have kernel level access to read your RAM and log your keystrokes.
