Building Expansion (Light Edition)

This mod makes basic district buildings more interesting by adding a unique twist on how they grant their yield, but without adding new building choices like the "full" District Expansions. Some buildings will give yield based on population, others a percentage bonus. See below for details.

This mod is for:

- when you are bored with how some buildings just give you +x of their yield and that's it, without any special interaction attached, and you want them all to be as interesting as the Harbor buildings (who doesn't love Shipyards?).

- when you wish that developing a city tall carries a bonus to just spamming lower level structures in many cities.

- when you are playing with the District Expansions from the Urban Complexity series and want buildings from the other districts to be up to par in terms of how much yield they can provide.

- when you want base buildings to be more interesting but do not want mods adding building choices out of fear that the AI will not be able to make the correct choices.

• Buildings not listed are buildings which I think are interesting enough with their existing special bonus already.
  
• Unless otherwise noted, the changes apply to the unique versions of these buildings, too.
  
• Policies boosting building yields now give +1 of their yield (+2 if Gold) per building instead of a +50% bonus, once for high adjacency and once for high population.
  
• Overall, make sure to check the descriptions ingame for details.

Requires Gathering Storm.

This mod is of course not compatible with other mods fundamentally changing the base buildings. Civilization reworks changing unique buildings should work, but might not update the description properly. Compatibility for Civilizations Expanded is included, however.

Compatible with Rule with Faith.

I highly recommend using this mod together with the District Expansions (this mod will only change buildings not included in such an Expansion active at the same time) and also the other mods from my Urban Complexity series.
