The argument “it looks worse so it should be cheaper” is kind of questionable, when the console they are buying it for just doesn’t allow for much better considering the art direction.
I disagree.
When you have to pay the same or more for something less then that's simply not justified for the consumer. If the console can't handle anything better and is that expensive to port over, then you should simply not port your game over to it. If that's a general Switch problem, then the Switch maybe shouldn't be a thing either. I thought that's how markets are supposed to work, no?
