Governor/Satrap focused Persia (or a Persia that lets you instabuild build a better-than-Antioch copy cities you raze)
Great Statesman
crazyeye
focused America.
France with a Foreign Legion UU that can be built with culture/tourism equivalent
Netherlands with a polder improvement that provides a Tulip luxury resource.
India under Ashoka.
Meiji restoration Japan.
Bismarck.
Palmyra as the oddball darkhorse.
Marcus Aurelius.
Gitarja returns, but with Gajah Mada that has a dual role as Great General/Governor
Yongle/Taizong China (taizong can get great works for winning wars or something, if great works return)
Science/Trade Arabia.
okay while I’m here:
great people can be selected from an era-appropriate pool.
immigration/melting pot mechanics that would allow for civs to build the UIs of cultures they have X% population of
great statesman GP that can generate diplomacy with CSs, fabricate cassus belli, or sue for peace, in addition to their unique abilities.
great people in general all have universal alternate abilities that for their type. Like Great Merchants can cultivate a copy of a certain resources you have traded for (Horses, Elephants, Corn, Timber, etc) or settle in cities as advisors to governors for bonus gold generation for that governor.
Modify governors so they’re not named and limited, allow for multiple governors of a single type to be created (perhaps they get more costly the more of one type you have).
incentivize adopting someone else’s religion, and spreading your own alternate version of it (see Protestantism vs Catholicism vs Othodox, Shia vs Sunni, etc etc).
Streamline the district system so that it’s 6-7 building slots per district, but you just have Urban (production/wealth/culture/infrastructure) Suburban(housing/growth) and Military districts (defense, units., Urban district on the coast would have access to Seaport/Waterpark buildings. Urban district next to/with road to jewels would have access to Jeweler building etc. Most wonders could only be constructed in a urban districts as well, to cut down on ghastly tile sprawl.
Ability to make goods out of raw resources.
Paper doll system for leaders so they can change clothing over time based on era, government, culture, etc. because it’d not only be nifty, but because it would help you know what a civ is focused on at a glance.
robust character creation tools so we could get more than 3 Alt leaders in the official game this time. To that end, no more voice acting.
Some kind of middle ground between 1UPT and Doomstacks. Maybe 5UPT? Archers + Swordsman would have the melee defense of a swordsman but have the choice between ranged attack and melee attack?
Navigable rivers.
Wonders that can be built on mountains and don’t just warp a mountain in out of the ether.
Government to be separated from civic focus, and each subfocus has their own pool of policy cards. (So you could have a Theocratic-Isolationist-Kingdom, or a Free Religion-Open Borders-Communist Regime, or a Atheistic-Meritocratic-Corporate Republic etc).
anyway, sorry, lost the plot there for a bit. I’d also wanna see Henry the V lead England, or if not, bring Lizzie back.
