Following the Mac release, you mentioned in a post-release blog post that Avernum 6 was outselling its predecessors. Given its success, how do you feel about your decision to end a franchise that's climbing in sales?

There are always regrets attached to ending a successful series, and Avernum has done very well for us. However, there is a fundamental limit to the process: If I can't write it, it doesn't happen. Seven games (Avernum 1-6 plus Blades of Avernum) is a huge amount of time working on one world, and at a certain point you get squeezed kind of dry. I've already gone too long without writing something all-new.

It's a big risk making something new, and I'm pretty terrified about it. But it's also really exciting to make a new world. I've having a lot of fun with it.​
