Indeed. Great game. I even got somewhat involved in the modding scene for it.
Speaking of games that would be a good fit, it's kind of weird/funny how Bioshock, supposed heir to System Shock, was so categorically rejected by the TTLG community at large, not just the more vociferous members, ahem. After all the dust settled, I'd wager even Invisible War has more of a following here than Bioshock (if one judges by the near-zero interest in Bioshock Infinite).
