Playing and beating System Shock 2 is like a core memory for me. It was one of my formative games that instilled a love for the entire genre it (and Deus Ex) formed. I would come back over the years and play a modded up version with better textures and visuals etc.
I am certain I will pick this up sooner or later and play through the whole thing again.
What am I, but a pathetic creature of meat and bone...
