City Building & Upkeep Extended - for Ayalin's Mod Collection

Goal:

Players will now have to prioritise increasing city capability vs growing city size and wealth generation vs funding armies. Naturally these priorities will shift over the course of a game.

Be prepared to use ‘build housing’ to quickly reach the next city size and get the competitive edge with city income and production bonuses, demolish buildings that are no longer required to regain the wealth used to operate them, and specialise cities so more wealth can be diverted to funding and producing specialised armies rather than building every upgrade available.

For those who have the wealth to support it, you’ll be rewarded with mega cities full of different upgrades providing buffs to your troops within your domain, and defensive buffs for your cities defenders.

Note:
Depending on your settings, this can slow down the game a fair bit in terms of expansion. Growth is now much more important and should be prioritised in cities you’re expecting to upgrade heavily.
Adjustments have been made to AI build priorities so their cities don’t fall behind the growth of the player.


Honourable Mentions:

This mod is inspired by some of the balancing in Empire Building Mod, which I used to play with a lot.
None of this would be possible without all of the hard work of Ayalin, whose Premium Empire Building Mod has provided dozens of new buildings to allow for meaningful choices in the first place, and is a hard requirement to play with this mod.


How it Works - City Buildings Have Upkeep (Building Cost Ongoing Resources):

-1 gold and -20 growth (undead/living) for all standard buildings, bonus buildings, class buildings, defensive buildings, and dwelling buildings
-1 gold, -3 mana and -20 growth (undead/living) for all Mystical, Heart, Shrine, and Ayalins additional Class Buildings
Buildings that replace their predecessors in the upgrade tree, have stacking upkeep costs to keep them in line with other upgrades. This includes Walls and Garrison Upgrades.

Notes:
-20 growth is pretty close to 22 buildings capping out a city's growth rate, assuming it has the Store House & Hospital upgrades (or undead equivalents). Other land marks, specialisations, and spells can increase the capacity further. Growth rate can't go negative and will cap at 0 growth (it won't go backwards), except for the high elves who will still generate positive growth if growth rate gets below 0.


How it Works - City Buildings Extended (Vanilla Building Bonuses):

Barracks gives additional +1 medal to irregulars

War Hall gives additional +1 medal to T1s

Guard House decreases the strategic movement of enemies in your domain by -8 and provides +25 happiness.

Great Temple gives friendly troops in siege battles +3 resistance against the first attack each round and Mind Control Immunity.

Grand Palace / Palace of the Perished gives additional +1 medal to T2's, T3's, and summoned troops. As a defensive buff it provides friendly troops in siege battles the 'Honour Guard' bonus granting them the Warriors Honour, and Killing Momentum passive abilities.

Wooden wall gives friendly troops in siege battles the 'Called to Arms' bonus of +100 morale.

Stone wall gives friendly troops in siege battles +3 defence against the first attack each round and +3 damage to their first attack each round.

Compatibility:
Requires DLC 2 and DLC 3, Ayalins Premium Empire Building Mod, Defensive Buildings Mod, and Class Premium Mods.

This mod loads in Priority 2 Slot, and will overwrite changes from any mod loading with a lower Priority. It should be compatible with anything that doesn’t change building properties. Ayalins mods have built in support.

I use this with PBEM, Chivalrous Intentions, all of Ayalin's mods, Marine expansions mod, and Triumphant Heroes.
Note that this mod will overwrite the cost changes made to buildings with PBEM, setting them back to vanilla values.
Chivalrous intentions and Ayalin's mods will really give you a reason to want to build some of the items you might otherwise skip. I highly recommend checking out all the mods!
