Here is the joystick article along with the legal document that you can examine for yourselves. While separately these elements would be fine but many of them are copied almost exactly. The graphical style, furniture, the Hud, exact same mechanics without any variations, and some of the animations. Include how close to each other in release dates and you got a case of blant copyright infringement.
