I love the art direction in the game overall (it is honestly the best part of the game), but as you advance through the ages and start to absorb more districts into your city, all your tiles start to feel very "samey." Some of the unique tiles stand out a bit, but otherwise it is largely a sea of the same color with some light blue or purple tinges for the science and stability districts. I'd love to see a little more color injected into the cities rather than a drab smatter of a single color. Production, gold, and food districts in particular feel way too similar.
