That's still not "archiving" though. It's one thing to download the installer, and quite another to install the game and copy the files hoping it will all still work. Especially on windows when registry entries are involved.
You have no clue what you are talking about. Registry entries that are required by games are like a thing of the past for like 25 years or something.
I am a heavy pirate and I my favorite games come as raw files torrents with the crack pre-applied. Games these days (with DRM removed) simply execute no matter where you copy and move them they just work. The cracks themselves do not modify any registry entries or make the game write them new or differently because they simply do not use the registry. Games write their savegames in AppData or Documents and THAT IS IT. Installers are glorified copy machines with ads on them (GOG) for example. They copy files and put a shortcut in your start menu and desktop and THAT IS IT, they do not write special registry entries for a game to work. Again this has not been a thing for like 25 years. I think it was when SecureROM was a thing.
So yes some steam games actually come DRM free, and you do not even have to move them out of the original steam install folder you just need to execute the EXE without steam running and they work. So indeed it is in fact achieving if you simply keep the files somewhere. For game with basic steam DRM you can use a crack or use steamless that basically removes the steam DRM that is very basic from the exe and use Goldberg Steam Emu to emulate steam. You do all this after the fact so you CAN for all the game that to not have some advanced DRM like Denovo just achieve the games files and make them work later on without Steam.
