No point and click? Nah, this game is a must-buy no matter what, BUT why not assign the camera zoom in/out to the mouse wheel rather than just mouse movement? It seems like players would make small up/down movements with the mouse without necessarily intending to zoom, so the camera would be constantly zooming in and out.
Yeah maybe we are missing something but thats what i thought too.. Mouse scroll seems alot better option and it's used in most of the games.
