You should give 
Darkness over Daggerford, for NWN, a try.
DoD broke all the records on its release last week. Fastest download count in opening 3 days, largest SP mod, fastest module to ever qualify for the the Hall of Fame, etc..
We did the vast majority of the artwork for BioWare that Ossian Studios licensed for use in 
DoD. The module (and the lizard huts!), however, are all theirs. 
The artwork includes a preview release of 
Tir Na n'Og, our 
magnum opus tileset.  NWN simply never looked this good before.  Here's a sneak peak :
  
DoD is in the same vein as Baldur's Gate 2.  Reviews for it are very positive, though it does seem to have quite a few bugs in the sub-quests off of the critical path.  (Beta-testing a 30 hour module is a beast.)
(Ahem: You might also look into grabbing copy of 
Wyvern Crown of Cormyr  when it is released at the end of the month.  

 I'd say it promises to be 
even better than DoD, but then again - I'm biased as all hell.  (Psst: It is, too!)
All-in-all, it's a great month for 3rd edition D&D CRPGs.
