Do u have to join alfa to play nwn on internet???

No you don't. Alfa is just a set of servers attempting to recreate as much as faerun in nwn modules as possible.
You can play NwN on the internet on any server or network.

I dig the new ALFA logo!!! I didn't want to start a new thread, but I thought I'd post the link here:
