AI:
- remove the restriction of AI not trading a Luxury Resource that they only have 1 of, but actually can trade it/don't neccessarilly need it because their Cities have plenty of Amenities. and Make Deals with Units Possible (Civilian and Military but not religious).
- Improve AI Naval Combat, like Naval Units joining Combat on Land by Firing at Units that are in reach, Bomb Tiles to keep the owner from working them, and immensely decreasing Strength of Land Units when Embarked, so that they are more vulnurable to Naval Units. Ideally make Land Units only cross Ocean/Coast/Lake by getting Transported by Naval Units (and make AI handle this).
- making AI more likely to conquer a Cities that own Strategic resources and/or Luxury resources they desire, from the early Eras till the Modern/Atomic Eras, with varying chances in each Era.
- make it not use non-militaristic Units for exploring the Map and collecting Goody Hutts.
UI:
- Aside from more Infos of the Items in the Tooltip (like origin of Resource/Greatwork(Products)...etc) inside Diplomacy Deal Screen, we should be able to switch off the deal Screen when we get an Offer and get back to it at anytime in that same turn, and remind us if we forgot it and clicked Next Turn (so that it doesn't proceed till we close the deal).
- Adopt UI and Flavor Mods like: Sukritact's Simple UI Adjustments/Civ Selection Screen/Global Relations Panel, Unique District Icons, Better Trade Screen, Better Report Screen, Better Deal Window, More Lenses, Enhaneced Mod Manager, Extended Diplomacy Ribbon, Better Loading Screen, Better Espionage Screen, Better Policy Cards and Simplified Gossip (Where most of what People want is already integrated/coded (and Up-to-date with the Game), so Firaxis just needs to implement them like they did with Map tacks).
- The Ability to select multiple Units and move them to a Plot, but with the Units distributed to adjacent Tiles and not stacking if they are the same Type.
- Make Civilopedia available in the Main Menu.
- City Production Panel: Queue Buildings that have prereq Buildings not built yet or damaged (need repair), and Queue Districts by also selecting the Tile for a District (Queue a District ==> City will force Player to choose the Tile for it or exit).
- Player Ability to change (all) Civs Jerseys In-Game (after all, it should be the choice of the human Player to switch Jerseys since it's just relevant for him/her, especially if the Game decides to change Jerseys of Civs that have similar main Colors (But I wanted Japan to be White/Red not Blue/White...

==> reroll the Game)).
