Liyon - What was that one PC game that came out in the late-90s that was a 3D first-person shooter, but you were inside a small craft and allowed full 360 degree movement ie. up, down, right, left. Anyone remember what I'm talking about. And you basically piloted the ship through tunnels and stuff. Game gave me a head-ache and made you constantly move your own head as you were operating the game controls, lol.
I've never seen that concept done every again.
