great job on the multiplayer in Metroid Prime 2", focus was centered on the single player portion of the game, which was considered to be "the core strength of the franchise". Art director Todd Keller declared the graphics to be focused in both texture detail and variety, with every single texture being hand-made and trying to "make every room its own custom stage".
