Yujah: Quite. Could somebody please just point out where that code should be / is or was for them? Reading stuff about "depleted keys" and all here on the forum, but for me there's just nothing to be found anywhere.

EDIT: Found it. It's not "here on GOG Galaxy", if indeed you are reading this through the GOG client, but on the web. Login to your account on the web, go to your library ("Games" under your profile header), click Wasteland 2 Director's Cut", Pick "More", "Serial Keys" and open the there provided link for the "Wasteland 1 gift code" in a new tab, choose "Continue" and add Wasteland 1 to your library,

Currently it won't in fact download ("server error") but that'll no doubt fix itself in due time. It is from that point in your library.

PussyDragon666: Won't show me more option anywhere except the galaxy. Where can i find it?

Lincoln_Ozis: Just bought and downloaded Digital Classic Edition and can't find code for Wasteland 1. Plz help

Well, found solution in another thread and its very unobvious

"...Go to your library on gog.com (not on Galaxy), click on ‘Wasteland 2 Director’s cut’, then ‘More’ and ‘Serial keys’. Copy and paste the grey link..."
