I'd say usually between 5-6, which would put them somewhere in the middle. That's one thing I always liked about Nintendo games, cultural balance. Take a game like Skyward Sword, it has the character designs of an old school 80's anime, mixed with feudel Japanese art, yet it has an impressionist painting look that feels very western at the same time. Or even games on the more Japanese end like Kid Icarus, and Fire Emblem, they have an anime art style with Shonen style story telling, mixed with the writing and dialogue of a smart and witty western cartoon like Adventure Time, Regular Show, My Little Pony, Gravity Falls, Futurama, old Simpsons, and old SpongeBob. And games with a more western approach like Star Fox still have a japanese flair combining cute talking animals with giant robots, space fights, and mecha. It's what seperates Nintendo from super japanese companies like Atlus, and very western focused ones like Sony.
