Actually playing it right now. It's cool and comfy, I remember reading a manual for it when I was a kid and enjoying seeing all the cool weapons described in it. I remember getting stuck in some sort of a tunnel race back then, didn't get to that part yet.
Also, for me it's FREEDOM:Diegesis. I feel like there's at most a thousand people who played it, even though it's a cool puzzle platformer with amazing atmosphere and even better soundtrack.
