I always thought more games should have used the gamecube shoulder buttons' feature. Analog and then a click before the bottom which allows it to be used for subtle followed by accurate/sudden actions. I can only think of two games that used it... Mario Sunshine (button was probably included just for it) and Eternal Darkness. Does anyone recall if a shooter did this for aiming on gamecube? I didn't play many shooters on there.
