NWN 2 didn't win me over either. I wish that NWN 2 was a bit more like NWN 1, possibly with a better graphics engine. As the game was actually handled, it seems as if we sacrificed a lot of options (not even counting PRC options) to gain prettier graphics. The expansions made some difference, but I would still rather play NWN with the PRC any day.
Oddly, even major companies don't seem to want to spend the time debugging, so they limit classes, races, feats, etc., to keep the structure as simple as possible. The funny part is that the PRC, relying entirely on volunteer labor, can pretty quickly squash bugs in the PRC, which just proves that a software company with even a mid-sized paid staff could create a game just as rich in detail as the NWN/PRC combo and keep it relatively bug-free. Sigh! No one ever will, though.
