Spaceship Procurements: Can buy spaceship parts with gold. Build spaceship factories in half the time.
(A)
We could add: when one of your spies sabotages a spaceship part gain that much gold.
I like your idea about spy sabotage. Late game, civs that have statecraft or built the national intelligence agency (which gives a free spy iirc) often have a ton of spies to use. What about something that would increase (+50%? ) the amount of yields stolen from other civs (probably without actually taking those away from your target but just increasing what you get) while also making your spies harder to catch (-10% catch rate? ). Maybe even throw in a bonus spy to make it easier to use.
I feel like this especially is a good way of making the late game feel interesting and different without disrupting balance because:
a) you still want spies in City States so you can't get that much value
b) it takes a while to establish spies unless you have high tourism
c) doesn't create a "first to tier 3 wins" situation
This is probably unfeasible at this point but it would be cool if you could spend a very large amount of gold (that increases exponentially) to level up your spies! I like the idea of playing a very wealthy civ that can use its influence from the shadows >
Treaty Organization: Gain 4 CS inf per turn with a CS you are trading with.
(C)
I would like this one to change to: gain +1 influence per turn in each city-state you have a franchise in, for each corporation office in your empire.
It's crazy to me that Freedom has no tier 3 tenets that affect corporations. I really like this idea of making corporations have diplomatic influence (like they do in reality). I would say, +1 per office may be a little high especially since franchises can't be pillaged like trade routes can. Maybe cap it at +3 influence per turn? Or make it so that franchises only give +1 influence per turn in city states you are not at war with and keep the +4 influence per turn with trade routes.
What about +1 vote in WC for every 5 or 6 franchises in foreign cities you have? Also cap that to give no more than 2 votes. That would make spreading your corporation more rewarding but would take a long time to come online and would only give a small bonus.
Dictatorship of the Proleitariant: +34% tourism to civs with less happiness. +1 happiness form factories.
Add: Civilizations not following Order have 10% higher poverty threshold.
or: Civilizations not following Order have 1% higher poverty threshold for each of your cities.
Not really a fan of this. There are no other maluses you can inflict on other civs and Order seems like the last that would do that. If this was gonna get any kind of buff, I'd say keep it simple like + 1 happiness from National Wonders to help keep high happiness for the tourism bonus. Also pretty thematic for Order.
Spaceflight Pioneers: Can build spaceship parts with Great Engineers. Gain an immediate GE and GS.
When you completing a spaceship part becomes a historical event with double tourism output.
You don't really need tourism when you're about to win a science victory... Again, I'd just keep it simple, maybe +1% of your science output as Golden Age Points to synergise with the science victory a bit. Late game Golden age points required are pretty high so at best this might net you one less turn before a GA so it won't really have an overwhelming impact. Might even bump it up to +2%.
Cult of Personality: +50% tourism to civilization fighting a common enemy. Free GP of your choice.
Add: Reset your war weariness every time a GP is born.
Seems like you could abuse this with faith purchased GP. The whole point of tourism for warmongers is to reduce resistance so instead of trying to figure out specific percentages for tourism, why not just add -1 turns of resistance when you capture a city. Or maybe only limit it to capitals and have -2 turns of resistance when you capture a capital.
Gunboat Diplomacy: Gain 6 inf with CS you could demand tribute from. Your military forces are 50% more effective at intimidating CS.
Add: When demanding tribute from a CS, gain +25 influence with all other CS of that type.
I like this idea! I would suggest lowering it to +10 influence boost and maybe raise the influence resting point for all CS by 5. Simple, engaging, and not overwhelming.
