They have clearly poured a mountain of design and engineering effort into squeezing every last drop of graphic fidelity and art out of the Switch. It looks really really good. Some of that is having the wisdom to choose an art style that works well on the Switch—a little cel-shaded, not a ton of texture detail. But, also, they really are getting as much detail and graphic complexity as they possibly can out of that little machine.

This isn't some cheap 2D pixel art game that spent their whole budget on game mechanics. It's a AAA game that maxed out their budget along every single axis. They just happened to target hardware with lower specs.
