I also find the game's aesthetic to be a dissonant mess. While I can put up with a more cartoony style, the UI is just too busy. Not only are there a ton of icons and labels on the screen, it was like the designers wanted to emphasize the civilization's colors rather than readability. The map looks strange because of how cities, mountains, wonders, and district buildings are scaled for visibility. Individual buildings look bigger than cities and appear as tall as some mountains or larger than some terrain features. Overall, the game seems to lack a cohesive and congruent style and it's ugly to me.
All that being said, I did like the variety for city state bonuses, having great people be more diversified, and the fact that needing a specific tile to place a wonder upon made it so that a small number of cities did not contain an absurd amount of wonders within them. Ultimately, I hope they make Civ 7 a more streamlined game but keep some of the variety.
