I bought Dying Light: Definitive Edition and received Dying Light: The Following – Enhanced Edition

You most probably have all the DLC's in your library .

It shows as Dying Light: The Following – Enhanced Edition in the library but you should have all the DLC's for the Definitive Edition.

yes they are all, I don't understand why another name appears

The Definitive Edition is a bundle of Dying Light Enhanced + all DLCs. As long as you get all the DLCs, there is nothing to worry about.

Because the website isn't programmed properly. It also does that same mis-naming thing with other games too, like Skyrim.

^this

The names are chosen very poorly. When the diamond edition was introduced, I was quite confused myself. But it's nothing but a bundle of the base game + expansion (called "the following") + a bunch of DLCs.

Some of the bundles have very idiotic names indeed.

Your library will always display the base game, which in this case is called Dying Light: The Following - Enhanced Edition.
Dying Light: Definitive Edition is a package that grants you the aforementioned base game plus a slew of DLC.

thanx guys. i

Did they include the Harran Military Rifle add-on yet? That was originally only available for Gemly users. Asked GOG a long time ago to see about it being adding it for everyone that's bought the game here but not heard anything. I already have it, so I have no other way of finding out if it's been given to everyone else.
