If NWN 2 isnt as multiplayer, PW, custom content compatible, I think its sales will die very quickly.
I played the NWN SP campaign for about a week before i found all the custom content and PWs. Since then I may have put 4 hours into the SP content (and that was only because my wireless network crashed and I didnt want to deal with it at the moment.)
SOLELY because of the custom content and PWs I and those closely related to me have purchased 3 copies of the game and all expansions, and I've reccomended the game to many of my friends, only because of the custom content.
Word of mouth is huge for games. If the word of mouth is non-existant or bad, the game wont sell.
I just hope they figure all this out before the game flops and we get nothing heh
