Era Buildings

Adds 9 Building-Lines to the Game with individual buildings within each of these Building-Lines that are appropriate to the Game-Era the player is currently in.

Highlighlights
--A player can construct and use an individual building from within one of these lines of buildings in their cities during a specifc era or couple of eras, but when they progress to a next era they would have to build a 'better' version from the same line of buildings, and the previous building from the earlier era(s) will become obsolete (ie, not function anymore) at some point during that new era.

--Buildings that become available with a new era are unlocked by a dummy tech that is given when the player advances to the next era.

--Buildings that are replaced by newer better versions go obsolete soon after a player enters the era that unlocks the new replacement building, but this obsoleting effect is tied to a specific tech within the new era, thereby giving a player a chance to upgrade to the new version of the building in cities where the old version exists before the effects of the old building dissipate via obsolescence.

--Having the older version of a building-line within an individual city allows the player a discount on the hammer and gold cost of constructing or buying the new version of the building-line within that same city so long as this upgrade is done during the Era in which the newer version is effective.

--As a player progresses through the game's Eras, the effects of the buildings are enhanced.

--Old Versions of the same "Building-Line" go obsolete, as mentioned before, and although there is a slight overlap between when a new version from within the Building-Line becomes available and when the old version goes obsolete, as a general rule there is only ever one building from within a Building-Line active within one city at any one time.

Balance and 'OP'
It might seem like a couple of these buildings are 'OP' in their effects, but just keep in mind what the requirements are to get and keep the effects of the building. The late-era food buildings might seem like they overshadow the Hanging Gardens World Wonder, but if you calculate your total investment in hammers you would have to make in your Capital, for example, to get and keep the Food Building effect within a single city from the Ancient Era to the end of the Information Era, it is not nearly so much an 'OP'. Hanging Gardens has a 'basic' hammers cost of 250, whereas if you build all of the food buildings in your capital city (as an example), by the 'Information Era' you will have invested 920 hammers to give an effect of +4 direct food and between +5% and +16% (depending on policy adoptions) total food yield. You will have to wait until the Renaissance-Era and you upgrade to the Renaissance-Era's Stock Yard before you are on a par for hammers invested and return on those hammers that will roughly compare to the Hanging Gardens.

Until or unless you complete the Aesthetics Policy Branch, the maximum you can get from one of the Happiness Buildings is +3 Happiness. The 'return-on-investment' for completing the Aesthetics Policy-Branch is High in terms of the extra and global happiness this provides for each of the Happiness Buildings you construct, but so is the 'investment' in Social Policy choices.

I'm not sure how much of those detailed explanations I can fit into a Workshop Description, hence the direct over to the CFC thread.

Screenshots
The Screenshots are taken from the civilopedia for the 'Happiness' line of buildings, and reflect the available Happiness buildings when this mod and Enlightenment Era mod are both enabled.

I'll be adding more screenshots in near future but at the moment I am have some issues with my computer which makes it a PITA to do screenshots.

Mod Compatibility:
--Compatible with Ultimate Eras Mod

--Compatible with Pouakai's The Enlightenment Era Mod[forums.civfanatics.com]

--Compatible with Novu's Prehistoric Era Reborn (20,000BC) Mod[forums.civfanatics.com]

--Compatible with Bouncymischa's Future Worlds Mod[forums.civfanatics.com]

--Note that while The Enlightenment Era mod and the Prehistoric Era Reborn mod, and Ultimate Eras mod are compatible to this mod, they are not compatible to each other.

--Mods that adjust the text displayed for various technologies might conflict with this mod to the extent that the text added by Era Buildings to techs in the tech tree might get wiped by the other mod, or vice versa. This sort of conflict will not actually have a functional effect on either mod. You just will not get tooltips and text that mention the changes made by both mods.

--Mods that make major changes to the existing Social Policy Branches or the Social Policies within a given branch might conflict in various ways with this mod.

--EUI: At this point I have no idea whether or not Era Builodings will clash with EUI or vice versa, but I cannot imagine why there would be such a conflict if one exists.

DLL Mods:
--'Stale' DLL mods will probably have a breaking effect on Era Buildings. Quite a few DLL mods are now essentially 'orphans', and have not been updated to conform to game patch version ~276. Any DLL mod that has not been updated since approximately Sept 2014 is probably not in conformance to game patch version ~276, and will kill this mod if both are run at the same time.

--Old versions of Civ4 Diplomatic Features will most likely break this mod. (non CP/CPB version: as I understand it there is a version rolled into CP/CPB that conforms).

Putmalk has recently released a new version of Civ4 Diplo Features for BNW, and the new version should not conflict with Era Buildings: Civilization IV Diplomatic Features - Version 11 Update[forums.civfanatics.com]

--Era Buildings might work with the CP/CBP but I do not know for sure one way or the other.

--W.Howard's Various Mods Components (VMC) mod should interact fine with Era Buildings so long as it is VMC version approx #62 or later. W.Howard is now up to V66 or V67 of VMC, so if you are still using an older version you should probably UpDate VMC Mod[www.picknmixmods.com].

Updates:
V12 : (1) added better compatibility to Prehistoric Era Reborn, and (2) added compatibility to Ultimate Eras mod.
V13 (this is the current version of the mod): (1) corrected compatibility to Prehistoric Era Reborn, and (2) adjusted the Seaport building to be a commerce-focused building.
