If you're into deep exploration first person games with well written world building and the feeling of unfolding a story as you play, you'll love system shock.

Now if you just think you're getting a traditional action adventure FPS and you don't really care about interacting with the world, you'll probably still find some enjoyment but this was not made for you.

System Shock is all about exploring all the levels of the Citadel Station and uncovering what happened while you were sleeping. And it never becomes tiring or like a chore - it stays interesting from start to finish, following a storyline as you go through the levels and find out more through audio logs and environmental touches.

I had an absolute blast exploring Citadel.
