I love GOG as a source for DRM free games, you're amazing! And I've purchased a NWN here, among other titles.

But I'm running a Linux OS, and I would like to play the game natively.

Unfortunately, native Linux client is no longer available via Bioware page, or at least I cannot find in all of the usual marketing BS pages.

Can anyone give me an advice how to play this game natively on Linux without downloading unverified 3rd party binaries?

I would really appreciate any help, the topics from 2010 are no longer valid.

Ok, thank you! I got it to work.

Extracted NWN install from Wine folder to a new directory.

Downloaded http://files.bioware.com/neverwinternights/updates/linux/nwclient129.tar.gz
Downloaded http://files.bioware.com/neverwinternights/updates/linux/169/English_linuxclient169_xp2.tar.gz

Extracted them in the same order over the NWN folder. Ran ./fixinstall, created the missing file, ran ./fixinstall again, updated permissions, removed the file I created.

Game launched, but with no sound.

Installed ia32-libs via apt-get.
Updated nwn file:
#export LD_LIBRARY_PATH=./lib:./miles:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=./miles:$LD_LIBRARY_PATH
This causes the game to use the systems SDL instead of included one. The game now works and the sound works.

Thank you for the assistance and ideas.

Awesome! Enjoy.
