>>38926067PS2 games had minor lighting, most details were just basic textures on low-poly models and the resolution was low.
It's obvious Sword and Shield aren't top of the line when it comes to graphics, but they're way more advanced than that, with dynamic stylized lighting on the characters, advanced effects for moves, reflections and fancy shaders, and foliage, something ps2 games didn't have.
At least people who compare it to Dragon Quest XI actually have some basis for it.
