The Community Expansion Pack is an enormous undertaking by the NWN community to gather the best and most varied custom content generated by the fans of the game. Bioware had nothing to do with this. The title of the project is something of a misnomer, at least in the sense that Bioware also created their expansion packs. Unlike in the Bioware expansions, however, there is no new game here, just new tools & content for builders to play with.

The concept is, that with all the custom content floating around, some enterprising individuals decided to gather up the cream of the crop and put it all in one big ole' download, so that people wouldn't have to bother downloading lots of little (or gigantic) hak packs to play individual mods. Also it saves builders the time of having to sift through the endless sea of stuff out there, and grabbing little bits and pieces of bigger hak packs, and combining them into the smaller ones that will go with their own mods. I've been through that process myself, and I can tell you, it's tedious.
