The smallest* repack out there! Download only what you want/need. You can install it on any version of the game, no matter where you got it from!
In short: already have base game? Skip "base-files.xbin". Already have some DLCs? Skip them! And then run "_setup-*.exe".
Longer instructions in README.txt.
"no-origin-fix-*.rar" is a crack from CODEX! Password is "origin-fix". Just in case your anti-virus deletes it and you have to extract it manually.
Thanks to Razor12911 for pZlib and XTool!
* FitGirl's repack is smaller but when there's a new DLC you need to download ~18GB again. With my repack it's just the new patch (3,2GB) + new DLC (size varies from 60MB to 1,9GB depending on DLC type)
