the Wii has enough controls for Tremulous. the nunchuk c-stick can be used for running/strafing, Z could be use, C for in-game menu. the main wii remote could be used for aiming, B for shooting, biting, etc., A for secondary attack, d-pad left/right-item select, d-pad up/down-use/equip item, minus-in-game menu. menu controls: B-comfirm, A-cancel, wii remote motion-move cursor
so yeah. i can say i have thought this out
