Civilization 5 Patch Update Introduces Replays, Hot-Seat Functionality, and More Challenging AI


Posted June 28, 2011 - By Leah Jackson


For those of us who still play Civilization 5 regularly, a huge new patch is coming very soon that integrates a ton of balance changes and a few requested features like a hotseat and replays. New features, diplomacy modifiers, and more challenging AI functionality was also added. To check out the full list of patch notes (there are a lot of them!) click after the break.


    * Pacing has received a large amount of work. Expect to have more of a challenge managing your empire at higher difficulty levels than you did before. Consider dropping a difficulty level if you have problems.
    * Existing saves will work correctly. However, the balance pass may make your existing happiness lower than expected when loading into your existing save post-patch.


    * Civilopedia now available in the Main Menu (under “Other”)
    * Replay is now available at the end of the game, and through the main menu. You can choose Map, Graphs, and turn-by-turn. Only games played post-patch will apply.
    * Great People progress UI addition (upper-left Info Corner UI).
    * Combat preview for Aircraft UI addition.
    * Fixed aircraft UI issue causing the aircraft selection UI to duplicate itself when rebasing aircraft.
    * When loading save game files, you can now order the list by name, or last modified.
    * Fix aircraft UI bug that was causing Nuclear Missiles and Atomic Bombers to leave behind container UI after it’s destroyed.
    * Removed dead players from Demographics UI.


    * Made backstab routine more transparent (the dialog will clearly state that they are backstabbing you).
    * AI now remembers when it has been nuked, for a permanent diplomatic penalty.
    * AI now recognizes a player that captured their capital for a permanent diplomatic penalty.
    * End declaration of friendship as soon as war is declared (so can't later get a notification that it has expired).
    * AI remembers if you satisfied one of their requests (positive modifier, decays over time, based on value of items granted).
    * AI remembers if you fought against a common foe (positive modifier, decays over time, based on damage done to the common foe).
    * Track trades between players and allow that to positively influence relationships (the better the deal for the AI, the stronger the modifier). Particularly useful for bribing a hostile AI.


    * Rebalanced AI flavors and strategies for unit training to improve AI army composition and build choices.
    * Allow the AI to consider Pikeman units for offensive roles when they can't build Swordsman or Longswordsman.
    * Allow Alexander and Darius to consider Hoplites and Immortals for offensive roles in early game.
    * AI players may now use a Great General in early rushes on higher difficulties.
    * Modified flavor tags for Atomic Bomb and Nuclear Missile so AI builds them only when it decides it specifically wants Nukes.
    * Block City States from building carriers, atomic weapons.
    * Strategies for building mobile units now persist into Modern era to help AI decisions for when to build tanks and modern armor.
    * Dampen early game Grand Strategies to give the AI time to expand (AI were sometimes stuck in a single city until late in the game).
    * Victory adjustments to AI behaviors, including alternate victory paths as “back-ups” (for example, building the Apollo Program, even if they are not going for a Spaceship victory).
    * Revise code calculating recommended army size (using smaller armies if the threat is low).
    * Correct issue that was causing late-game continent-bound AI’s to over-build units intending to invade, and never properly execute the amphibious invasion.
    * Scale recommended army sizes based on difficulty level.
    * AI grand strategy and flavor weighting balance pass.
    * AI policy choice weighting balance pass.
    * AI tech choice weighting balance pass.


    * Player is now given the option to return a CS worker that they free from barbarians.
    * Roads under captured cities no longer charge maintenance.
    * Machu Picchu no longer destroyed when capturing a city containing Machu Picchu.
* Fixed Oligarchy bug that was causing the effect to expire when loading from a save.


    * Multiplayer AI is now consistent with Single Player AI.
    * Hot-Seat is now available through the multiplayer menu.
          o You can have as many humans playing as available slots in the game.
          o Password protection is built in.
          o All maps, including purchased and user-created, are available to play in Hot-Seat.
          o While play-by-email is not yet implemented, we did include an in-between turn saving option for those that want to play via email.


    * Policy “Finishers” added to all 10 policy trees. Taking all policies in a tree will grant an additional bonus effect. See policy notes below for more information.
    * Tweaked Policy cost formula (cheaper earlier, more expensive later).
    * Reduced per-city Policy cost increase by 50%.
    * Culture from City States tweaked (less early, more later).
