I already own 2 copies of NWN Gold (NWN+SoU+HoTU), I don't need more of that. What i do need are the Premium Modules, and not just Kingmaker, I'm more interested in Pirates of the Sword Coast and Wyvern Crown of Cormyr

As many know, the Premium Modules for NWN are no longer sold separately, either at the Atari or Bioware store. Neither Atari or Bioware have come up with a convincing explanation. Bioware blame Atari, but they always do that.

You could try just downloading the premium modules reinstaller thing after you buy it, it may install them completely, it may just update them for your cd key, I'm not sure.

Also, the installer may have an option to only install that part of it.

If neither of those work you can always install over your current copies, just make sure to back up your saves(though I doubt it would even touch them).

Yeah, it is an issue where Atari has rights to the income from the sale of the Premium modules (Atari has the license?) and I guess Bioware is now owned by EA, a competitor. I guess it was too complicated to work out the method of ensuring the profits went to Atari... IT could have been a license issue as well, how do you "share" a DnD license with another party?

Each module is considered a licensed product, and your CD key has to be registered with Bioware in order to access the Premium module content... I'm not sure NEW people can play the Premium modules. I have the modules and access to play them, but I bought them way back when. :(

There are so many fan made mods, some of them arguably even better than the official ones, that you should be able to find enough to satiate your NWN needs.

It does stink that Atari made Bioware stop selling the official premiums but I highly doubt you will ever have a legal means of getting them.
