playing USUM in citra in HD opened my eyes to cel-shading being integral to this game's style.
Don't get outlines and cel-shading mixed up though. The game looked best with the outlines patched out. But even with outlines, HD pokemon 3DS games look amazing, and it makes me wish they'd just drop the default blender viewport shading + rim-lighting that they've been using for every game released on the switch.
