Just got around to catching up on some of the articles that I missed last week. Even though most of these interviews just contain information we already know, it's still nice stuff! Thanks for posting!
Craig Zinkievich: Maps themselves are pretty large. I don't have square kilometers handy, but our space encounters always take place in fairly large environments. We have epic ring worlds, asteroid belts, devastated planets, blazing stars, perilous nebulae... Those are big things. We try and convey the enormity of space, but in a way that makes sense for the fiction and plays well.
