Yeah, Diamond Edition doesn't have Infinite Dungeons... Which is, I'm sad to say, the best one, if you have friends who just like to use NWN as a dungeon-crawl, diablo-esq game. If you liked NWN for the story-based modules, it's pointless though.
And like a poster below me, I'm re-downloading an archiving it right now.
