I got good at it back in the day. Still found the controls awkward as hell, but that game (and later on its successor Perfect Dark) had hours and hours of gameplay because it was one of the best fps games of its time (that wasn’t on PC where wasd and mouse was already a thing right from the Doom days).

Halo was revolutionary. One stick moved, the other rotated, plus grenades were always a button away (in GoldenEye, the rare times you had them, they were selected like any normal weapon, which limited their versatility. Proximity and remote mines were way better.)

Metroid Prime also had a really awkward control scheme on the GameCube.
