Thanks! It did indeed; it took me a while to get used to it. Something that helped was that before I got into System Shock I had dabbled in level editing for System Shock 2, and movement in the editor used a similar control scheme. But it's still a lot to wrap your head around when we're so spoiled by mouselook today.
Ironically, mouselook somehow doesn't feel right in System Shock. I believe I mentioned in one episode that someone managed to hack it in. It works great and the guy should be forever lauded for his extremely hard work, but somehow it just doesn't feel like it belongs. But then, System Shock also uses its laborious controls to its advantage; they create a much more tense atmosphere; you have to be more careful, because if an enemy surprises you, you can't whip around and shoot quite as easily as you can in today's games.
