9: Steel Battalion
This is an odd one. The game is mostly remembered for the additional gadget that came with it, a fully fledged mecha cockpit control unit. Also, while being a game for the original XBox, it is also one of the few Japanese games on the platform. And one of the very few really hardcore simulations available on any console. The game simulates being inside a mech’s cockpit to a tee. Almost surprisingly, the emergency eject button does NOT kick you off your couch.
