It isn't "literally" a 2D space. It is "topologically" a 2D space in that you could represent it as a 2D space without loosing information. It doesn't provide 6 degrees of freedom but it is very much experienced as a 3D game environment. EDIT also, using the term "literally" to talk about 3Dness when it is all rendered onto a 2D screen, is fairly precarious. No matter how many degrees of freedom, or how rendered, it will never be "literally" 3D, in the literal sense of the term.
