even better idea for wii mmo controls (not necessarily runescape, just... in general)
the entire game is played from a first person perspective. the wiimote controls more technical things like targeting enemies to start wailing on, switching to combat stances, opening up your inventory, checking your stats, things like that, and the nunchuck lets you interact with the world, by doing things like moving your character around and using 'free look' to look at targets while you're moving in one direction
instead of pressing a button to fight or pick up things 'n stuff, your wiimote and your nunchuck effectively control the player's hands: you could reach for an object like a sword or a shield, then grab it with c (for the nunchuck, or left hand) or b (for the wiimote, the right hand), and then if you're holding something you could press the corresponding button again to either let go of it (hold down the button) or simply put it away in your inventory (by just tapping it): if you let go of the object with momentum, like in a throwing motion or something, you would hurl it at an invisible 'crosshair' in the middle of the screen (which stays oriented in the direction you were looking when you started holding down the button). the power of the throw would be determined by how hard you swung down whichever arm you're using, and it would curve if you were to move your arm like you were throwing a frisbee or something.
if you were to press a specific button on the nunchuck (i really wanna say z, that seems intuitive enough), you would switch the control scheme for interacting with the world- the one i just described is the 'passive' mode. the only other mode is the 'active' mode, which lets you do things like swing the thing you're holding, lets you swing your fists, and instead of dropping things, the controls for dropping things switch to context-sensitive 'alternate modes' for weapons: like, bows would be aimed and you could see the crosshair in the middle of the screen. swords would be pointed toward the crosshair, same with pikes. in fact, most melee weapons would point to the center of the screen- even things like axes. shields would 'buckle down', letting you actually defend against things rather then bashing them with the shield or something. two handed weapons on another note have an entirely different control scheme in active mode: in passive mode, they're held with one hand for ease of use, but in active mode your weapon is held in both hands, and the nunchuck defines which way you point the sword while it's at rest. by that i mean, not hitting anything.
stuff. wait. are we even talking about wii control schemes? i lost track on the second paragraph
