It's funny, because when System Shock originally came out I couldn't play it because I couldn't afford a good enough PC to play it (I only had a black and white laptop at the time). Then I ended up getting a job at the company that made it and then I ended up working on the sequel! I've had a lucky life.
Yeah I figured the Citadel expansion was a love letter to System Shock 2. As soon as I saw the mutants and heard what they were saying.
