It's all in 3d but with Toon shader regardless. Can be iterated on. It would be nice to afford better more complete graphics. But getting the game done is more improatant.
if you're going to invest a lot of time into something as big as a game project, why do anything quick and dirty? Doing things properly will give you better results and be faster. IMO the earlier iterations with lighting and textures are a lot nicer. Nanite is not equipped to handle characters yet, iirc
