I've actually had to stop playing for the evening, and my real arm feels weird, like it's a bit too heavy. Never had such a strong reaction to a game before.

Brilliantly done, that game.

That makes me think of the game Breakdown, which had the best implementation of body-awareness yet. The downside was that the player character steps out into hallways like an idiot when you open a door. "We're in an extremely hostile area, yet we can't just turn the knob and shove the door open."
