You can actually throw any weapon. But I think it destroys the weapon most of the time so it's a better tactic to save until the weapon is near breaking anyway.
That adds a whole new depth of strategy behind fights :D I love it :D I'm only hoping that spears will do more damage if thrown than swords and things like that.

Furthermore, I think VGChartz should add a "Like"-button.
