This post just reminds me of these games from The Legend of Zelda. I'm gonna go real in-depth on the games, so bear with me, I'll bring it back to the topic lol
So, back in 2000, there was this tech demo for what looked like a more realistic (at the time) visual of Ocarina of Time to show off the hardware capabilities of the Gamecube, and like, everyone was hyped as hell. 

2003 came around, the trailer for Wind Waker came out and there was mixed reception. Fans wanted a realistic game at the time, and Wind Waker's cel-shaded graphics looked cartoony to the general public in comparison to that tech demo. Some hated it, some loved it. People arguing on whether Nintendo was starting to cater towards children more than the adults, and so on.
Nintendo was like, "Ok, we heard you guys." and in 2006, Twilight Princess happened. Fans were ecstatic, everything looked so realistic (at the time) and the overall artstyle was basically semi-realistic anime and it looked like the series was gonna take a darker turn and cater more towards adults.. so yeah, everyone was happy, pretty much.
But... the years went on. People's views have changed since then, other games came out looking more realistic, and Nintendo settled for a hybrid of realism and cel-shading (and a watercolor painting aesthetic) for Skyward Sword.
Afterwards, they went and made another hybrid of their artstyles in what we would see from their next game, Breath of the Wild.
So, what does all this have to do with the post?? Well, there's people that have gone back on the Twilight Princess realism in favor of Wind Waker's cartoony look! One major part of the reasoning being that the limitations set on the hardware combined with the artstyle and it's lack of saturation made for a dated look that tried to hard to be real for some people. They've seen how much better the realistic approach has become in recent years, and Twilight Princess pales in comparison to these new games.
The cel-shaded graphics of Wind Waker can't age as much because it went away from realism, even if the game came out before Twilight Princess. The overall expressive nature and simplicity of it is essentially why people still love that artstyle so much. Skyward Sword aged too, but only because of the limitations of the hardware, not the artstyle itself. And it all comes together in Breath of the Wild. The cel-shading was perfected, the models have become less polygonal looking, the colors stand out, the textures have upped their resolution, the detail is outstanding! It's an impressionistic psuedo-realism and it seems to work! Seeing as I haven't seen anyone actually complain about the look of it, I truly believe this will be the next game that will stand the test of time from Nintendo as far as the artstyle goes.
Back to the topic at hand, simplicity can definitely go a long way, and complexity can too. The mix of both can do the same as well. It's the execution of it that matters more in all of these cases. Simplicity in the wrong hands can come off as crude and poorly drawn, complexity can come off as unnecessarily detailed and a strain on the eyes. That mix can be seen as indecisive and settling for in between. There's an audience for everything, and in that same strength, there's critics for everything. None of these should have any superiority over each other anyways. Good art, bad art, amazing art, horrible art, it's all subjective. But at the end of the day, the artist has to make something that they themselves can be happy with, and in doing so, I think the audience should respect that much at least~
