Neverwinter Nights is a commercial role playing game based on Dungeons and Dragons. A native Linux client is available:

http://nwn.bioware.com/downloads/linuxclient.html

Neverwinter Nights requires OpenGL drivers.

• There is much discussion / concern with respect to ATI and NWN drivers. It seems that the drivers direct from ATI have a bug when run with the 2.6.xxx kernels, however Fedora Core 3, with appropriate updates, runs very well.

• There is a new version available - Neverwinter Nights 2. This is NOT Linux compatible, there is No Linux binary for it. The original NWN, with Linux binaries, is still actively supported.
