I'm playing it and loving it. The party system is more interactive than the original and its probably the most enjoyable D&D experience I've ever had on my PC. It's also got a really great editor so you can create your own adventures, its very user friendly. I'm curious how many of you have played it? Here's a review in case you're curious.
