It's not even a useful debate. What useful framework can you put up on either side? I could see arguments over puzzle quality, mechanical control, difficulty, money scaling, whatever. Civ 6 has equivalent versions of that too. The art style doesn't have that kind of backing, on either side of that particular fence.
I can't even grasp the rationale though. Is the complaint that these games with no true real world parallels don't look sufficiently realistic? Too realistic? I get complaints if the art makes two different-functioning things look similar or vice versa, or if the game is incongruous within its own framework (IE putting the master chief as a story line character in Wind Waker exactly like how he looks in Halo, yet everyone else in the game acts like it's normal)...but over the style itself? It's the kind of preference that's pure perception stuff.
"I know your opinion is wrong. I know this because you have stated that you have a different opinion than my own". It's fun to say to troll people, but there's no actual discussion there. I know visual experience is part of the immersion, but the designers have to pick SOMETHING, and that means it's not something else :/. I guess if it's a major barrier then w/e, play stuff that looks nice if that's sufficiently important.
