There's a new interview on GameBanshee with John Morgan, Ferret Baudoin, and Chris Avellone of Obsidian. It's mainly about NWN2, but there are some relevant bits to post-apocalyptic things, namely the final question:
GB: To conclude, where would
you like to take Obsidian Entertainment over the next 5 years? Any
particular games you have on your "wish list" for the future, such as a
new Planescape RPG or maybe a new post-apocalyptic title?
JM: Obsidian Entertainment is finding its place in
the industry and is growing at just the right pace for our tastes. I
see the company only slightly bigger in the future because when you
reach a certain size, you have to hire extra people to manage it and
keep the general bureaucracy of the company going. Where we're at now
feels like a large circle of friends where everyone knows everyone else
and we genuinely enjoy spending time with each other, both at work and
after-hours. It becomes more difficult to keep that unity going when
you reach that ambiguous size as you start to get people who rarely
interact with each other simply because they have no need to or there's
just not enough time. We'd like to avoid that and find the sweet-spot
where we are able to maintain a few projects at a time, in different
stages of development, and keep making games on our own terms without
having to worry about all that nasty game development red-tape.
I feel that's a fine bit of question dodging.
