Jeez, Palworld doesn't have any concept art at all. There's literally zero 2D concepts, documents or anything of any kind. They apparently STARTED designing with 3D models and, what do you know, they're almost directly lifted from recent Pokemon games with some slight alterations.
Who knew a crypto/AI asshole CEO with a company that literally didn't include artists and didn't know what 3D rigging was could manage to put out such a feature rich game so quickly.
I WONDER HOW?
