NeverWinter Nights

Okay, so I was going through some old shits from my windows days, and found a manual for NeverWinter Nights: Platinum, which is NWN and its first 2 expansions (of what seems like a zillion).

I'm downloading the linux client and am planning to install it. I don't have a CD, just the CD keys, is there anywhere I can get the data for the expansions I have keys for?

Also...how many expansions have they released now? Would it cost me a zillion dollars to be up to date? I'd like to start playing again.

Neverwinter Nights has two main expansions (Shadows of Undrentide and Hordes of the Underdark). There are also a few premium modules you can download on the game's official website for a price; then there are numerous player made single-player and multi-player modules available at various places.

As for the price, I got Neverwinter Nights Diamond Edition for $20 and it came with Neverwinter Nights, both expansion packs, and the Kingmaker premium module.

EDIT: Found information on getting game resources,

Read here for information on getting the game's resources for the linux client:

I'm downloading the Neverwinter Nights Linux client right now. A 1.1 gb file, will take a couple hours, and it prolly won't matter for a while, but I do have CD keys for both Shadows of Undrentide and Hordes of Underdark here in my manual. <edited out due to breach of the CoC>

Won't matter for a while, though, I'm sure the ordinary game can keep me busy for a long time.
