Obsidian Entertainment - Chris Avellone Interview @ The Guardian

The online site for The Guardian has an interview with Obsidian's Chris Avellone covering a variety of general topics.  I'm thinking this is a part tongue-in-cheek answer about NWN2 but you can decide for yourself:

TG Any specific feature of which you're particularly proud?

CA I think the water. It's great, because while our coder was working on the water, he made sure that all the variables about the water can be tweaked by the designer. For example, if you remove the choppiness, slow its rate down to a crawl, make it very viscous, and put on a molten-red texture, then you've got lava.
