What is your experience with Neverwinter Nights?

I've been playing it on and off for, oh, about six months now. It's a blast from the past for me -- it's been about 20 years since I last had anything to do with D&D -- and some of the rule changes from 2nd edition AD&D days took me by surprise: armor classes that make sense, for example! It's a surreal experience in some ways, too -- getting beaten up by a bunch of Red Slaadi at one point in chapter two of the official campaign. ("Hey, I invented you!")

On the other hand, I've managed to avoid getting sucked in too far by the simple expedients of (1) refusing point-blank to go on-line with other players, and (2) running it on a Mac, which puts 90% of the content-creation kits safely out of reach. This is a good thing, insofar as I work from home as a writer, and if I let go I'd end up blowing through deadlines like... [tasteless metaphor to hurricanes and levees deleted].
