EpsTweak for Tall Play

EpsTweak is a series of small mods that tweak the balance of Civ 6. Rather than put all of them into one hefty package, I’ve split them into small fragments to allow you to make your own custom rulesets.

Out of all mod types, a tall play mod is by far the most popular thing people have requested of me. So I’ve made my best attempt at a lightweight solution that enables you to compete on a small number of cities.

The way it’s designed is that there are 4 core tall buildings that give you a big boost to science, culture, economy, and faith respectively. However, you can only have 1 of each in your empire, and they come at a price – after they are built, they make the same district type in other cities worse. Build all four, and you’ll find yourself hesitant to build those districts in your non-core cities at all, which in turn makes founding extra cities less appealing. Beyond the core 4, there is also an extra 5 buildings that specialize the tall cities even further, along with a special Policy that will help you grow your population.
