Neverwinter Nights 2: Storm of Zehir Interview

IGN's Neverwinter Vault has conjured up a quick Storm of Zehir interview with Obsidian Entertainment's Scott Everts, Matthew Rorie, and Nathaniel Chapman.
Is there much replayability to the expansion? Baldur's Gate and other older classics like Pool of Radiance are often played over and over by folks I know, simply because of the quality of the experience or because of how their imagination was captured during the first time through.

Nathaniel Chapman: I think so. I think the Full Party Creation and Overland Map really encourage this. In the end, though, the players will be the best judge of that. I know that after finishing my playthrough I wanted to go through and try a different party build... there's a lot of replayability just in what kinds of characters you make, especially with the massive number of classes, races, spells and feats available in NWN2 now.
