I kind of learned 2nd Ed and 3rd Ed rules at the same time since 3E was coming out when I was learning how to play BG2. Overall, I know 3E much better since I play table top pnp also - which isn't saying much since I'm no expert.
Thanks for those other review... I've seen 3 or 4 reviews now - I'll have to check yours to see if they are repeats. Generally, everything has been positive with few negative comments really. Looks like a very good game and IWD fans will consider it a must buy.
BTW folks, if you haven't bought it yet, I received word that it is on sale at Kmart for $39.95... thats $10 off MSRP and I doubt you see it much cheaper for quite a while.
