Life On Mars?

I really enjoyed Life on Mars?, and found it to be a surprisingly immersive experience, even though it's not a terribly interactive game. This sounds counter-intuitive, perhaps, but because of the situation the PC is in, the approach felt very appropriate and was executed very well. I was less keen on the later game, but feel that this game is definitely worth playing for its somewhat novel approach to revealing backstory. Clearly the author put a lot of effort into this, and it paid off with a haunting experience that generates a great sense of empathy in the player.
