Im not sure why i want to do this by i find it annoying to have to reinstall a game with every new computer and console ive gotten over time. How would one make a offline installer or backup, I would also want to make them look like retro media if possible.
By chance are there better ways of re installing games without torrents?


Get the games from GOG wherever possible. No DRM and easy to use installers.
You should support them, but if you don’t, their installers are still DRM free and easy to install from! Also if the game is bigger than 4.3GB they break it up so you just keep inserting the next disc.
Safe to say my Steam library is DRM locked? Is there anyway to migrate?
Different games use different types of DRM. If the game just uses the basic Steam DRM, you can remove it with Steamless. If it uses something else, you have to wait for someone to crack it or for a DRM free release.
Steam has its own DRM, in addition to DRM added by the manufacturer. So at the very least it’s going to ask Valve if you’re authorized to run the software. Whereas GOG doesn’t do that. (Steam can also make backup installers.)
Not necessarily, there are games that you can run directly from the installation folder without having to start Steam.
Nope.
