I have been beaten, I see.
System Shock 2 was ahead of its time in
its respect of the player: It only took control from you two or three times in the entire game (the ending cutscene included), and you could interact with practically
anything in the environment: pick up and toss mugs, fill your inventory with magazines,flush toilets, change what's on the displays scattered throughout the Von Braun, etc.
It also had three distinct career paths, all of which changed your playstyle drastically: marine path lets you focus on conventional guns, navy path lets you focus on hacking security systems, chests and turrets, OSA lets you use psionics (the progenitor of Bioshock's Plasmids, think of them as sci-fi magic). Oh, you get 97% of the story from audio logs and text scattered around the station, by the way. One of the first games to do that (right after the first System Shock).
It's grossly underappreciated. It's basically a perfect 20-hour RPG FPS (or, as I like to refer to the genre, immersive sim).
