Follow up to the NWN module recommendation
this is a nice little story-based campaign (with a sense of humour and a sequel campaign if you like this one)
But if you want something darker then I've just finished
this by the same author. Wonderful piece of work. So much so that I started into
the sequel (which has a very nice opening section) almost straight away.
If you get the NWN bug from these then I'm sure there are plenty of people able to recommend other modules and other authors around here. I know these forums house a few other fans of the game.
