Jarmo: There's a generic CD-key included in NWN1 dowload which works for all singleplayer stuff, for some funky reason one needs an unique key for multiplayer.
Darvin: It's because the CD-key is used to uniquely identify players. This makes it technically impossible for two people with the same CD-key to be in the same game.
Jarmo: NWN authentication servers are shutting down this month and I'm all unsure of what that means for multiplayer gaming.
Darvin: Nothing; it just means the auto-patcher won't work, so people with physical copies will need to manually patch. The NWN multiplayer community has been fully independent of any official servers or support for some time.
The only thing that's going to be lost are three of the premium modules that are dependent on an authentication server. Infinite Dungeons, Pirates of the Sword Coast, and Wyvren Knights of Cormyr were all DRM'd (unlike the previous three premium modules, which got physical releases) and will stop functioning when the servers get pulled down. These three modules are not included in the GOG release.
I got the three premium modules (Infinite Dungeons, Pirates of the Sword Coast, and Wyvern Crown of Cormyr) elsewhere, and they are still functioning on my computer. They can be played just with the CD-KEY from GOG. Perhaps the server for DRM checking is independent?
