Hard disagree. The district system of Civ 6 was half-baked, and the new one for Civ 7 seems way more interesting with districts growing more organically. Civ 6's world congress was garbage. The eras system needed serious work as dark/golden/heroic eras just didn't feel impactful enough aside from getting a monumentality era early. The new map generation with navigable rivers is a huge plus as well. The climate system in Civ 6 was a dud too, not nearly impactful enough. I think they could've made a Civ 7 which fixed all the broken Civ 6 systems and made a great game.
