Seriously, the game is like 90% there: [video:google]

Personally I really like exploring the world this way, but it's quite cumbersome at times because there's no real third person camera support.
I'm not sure of the effort involved from a technical point of view, but from the user's perspective it seems that we just need support for:
a) Controlling the movement of the selected character with WASD
b) Controlling the camera with the mouse directly, without having to keep the middle mouse button clicked at all times
