Why everybody are so keen on making re-spawning civilization to be playable? Greece can respawn between 1800 AD and 2020 AD (Const.py line 499, you can check that yourself) if civilization that control its core is unstable and have Nationalism but not Imperialism civic if I remember correctly.
Not playable because IMO it isn't interesting and/or history-changing enough to be playable.
Oh, and EU is an organisation, not a civilization. Unless this game called Organization IV and the base mod is Rhye's and Fall of Organization, I think it shouldn't be added.... and also you should suggest adding ASEAN, Arab League, and African Union "civilization" as well if you want to add this EU "civilization"
Spoiler :However, I think the idea of EU as a mechanic is quite interesting; in the model of AP/UN, acts like the regional UN, give effects only to specific region (like EU policy of adopting Universal Suffrage will only affects European civilization) and building it + become leader necessary to win Diplomatic Victory. Example of this could be EU, AU, ASEAN, SCO, NATO, and many more..
I opened this thread to discuss about European Union. We can represent it as follows:
*A civilisation (that will spawn on half of Europe, it would be fun, especially if you want to play a short late domination game )
*A permanent alliance
*An Apostolic Palace/UN mechanic
Maybe the best option is the last one so I'll make the start and propose how I think now it should work:
*The european parliament will be enabled by mass media. It will require also a european civilisation, universal suffrage and being at peace.
*When it is built all european civilisations that aren't in war and run universal suffrage will be questioned to join European union by a YES or NO question. AI's will always join EU except if they run a really strong economy. Members state will lose all their vassals.
Resolutions:
*Presidential elections similar to the UN and apostolic palace.
*There won't be diplomatic victory resolution, because it is a regional organisation.
It can be replaced by a permanent alliance resolution which will be equally difficult to win. If it passes then European Union will become a permanent alliance.
*Accepting member resolution: If there are candidates the president will be forced to choose a candidate for an acceptance resolution. The resolution will ask members if they accept the candidacy. Candidate will be asked if they want to become a member. AI's will accept the candidacy if they are friendly, pleased, or cautious. They will abstain if they are annoyed and refuse only if they are furious. Candidate will just be asked a YES or NO question if they wants to join European Union. AI candidate will accept the candidacy, and there may be a possibility to refuse it if it has a really strong economy. If the candidate becomes member it loses all the vassals.
*Single currency resolution: +1 in all cities, great depression more effective
*Single constitution resolution: all members are forced to switch to republic
*Evironmentalism act: all members are forced to switch to evironmentalism (then the free market civic required will become evironmentalism)
*Euroarmy resolution: equivalent to defensive pact
*Erasmus: +1 by universities
*Space programme resolution: combined Space victory win. The members will be able to construct a different part of the spaceship. The president may ask for a launch resolution and the members will vote. If the EU wins a space race victory and the player is member player wins. If not then...beware the EU!
*Scientific cooperation resolution: combined all technologies held by members revieled to all members
*Eurodiplomacy resolution: European Union will work as one civ in diplomacy. President can handdle other civs diplomacy screens and members will vote for the final decision of every agreement.
In order to become a candidate civ requires:
*Be a european civ.
*Run universal suffrage, free market and secularism.
*Not being at war.
AIs especially the weak will try to become members at top priority.
Other effects:
Effects due to EU being an economy union (single market, freedom of transfering goods, capital, labour and money):
*+1 "traderoute: to all city members
*access to the benefits of all resources (apart from building weapons) (but it can not be traded if not possessed inside the cultural borders)
For example if France has Uranium and you control only Italy you can build a nuclear plant but you can't build nukes, nor trade France's uranium.
*+25% in trade routes from members' cities
*backyard civilisations will be able to investigate techs that are discovered by other members at signifficantly lower cost
Effects due to EU being a political union:
*cannot change required civics
*+1 hapiness to all cities
*+2 stability per member state to all members
*no unhapiness/revolt issues by culture of a member state, no stability issue from culture in member's territory
*+3 friendlier attitute towards the members
*cannot declare war among members
