If you have to crack the DRM, it’s not DRM-free anymore.
The ones that are copy-and-paste-the-files-and-run-them, sure. But just because DRM is easy to crack doesn’t mean it’s not DRM.
(The one exceptions might be those super old forms of DRM which basically just need the manual and that’s it. Sometimes, those were actually done in creative ways that made narrative sense in the game, too. So those are like, obsolete DRM that’s auto-circumvented.)
