Just trying to help... When planning cities I find Civ 6 encourages building cities close together First reason: Production. Factories and Power Plants give their production to all cities within 6 tiles! You must use this mechanic. (later in the game some entertainment district buildings also give amenity bonuses to all cities within 6 tiles) Second reason: many districts give bonuses based on how many other districts they are adjacent to. This bonus is not limited to districts of the same city. build your cities close together. connect your districts. get more yields. When laying down cities Civ 6 encourages you to plan ahead more than any other version of the game. You need to consider the grid. Try to put your districts in a central location between at least 3 cities to maximize benefits. Below is some rough images I made on MS Paint to describe what I mean. The black dots are cities. The Orange dots are factories. The yellow dots can be what ever suits (commercial, cultural, campus, entertainment). The numbers show how many other districts they touch (the bonus received is 1/2 per district). With a simple triangle grid formation each city is getting at least 18 production with factories. Once you have your initial grid built then you can join more districts for more bonus such as a harbor next to one of the commercial zones.
