Wouldn't it be so much cooler if the weapon (ex. sword) of your character maps the movement of your mouse and translates it in-game (with the use of accelerometers). There will also be some guidance in the game software itself so as not to make melee combat too difficult. For example, a quick backwards to forward movement with the mouse while pressing the attack button (left-mouse button) will make your character lunge towards the enemy.
So, what are your thoughts?
