Advanced Civ

Advanced Civ 1.10

An extension of K-Mod. The bulk of the changes concern the AI; a few balance changes; practically no flavor changes; no added content. Multiplayer is supported and has been tested – but not thoroughly.


Rewrite of the AI parts dealing with decisions on war and peace; revision of AI relations modifiers; some rules and balance changes, mainly to address loopholes; overhaul of Barbarian placement; culture of dead civs stays in the game; various AI and usability improvements; game options "Rise & Fall" (periodically take over a different civ from the AI), "True Starts" (civs chosen based on the geography of the starting locations) and "Start Points as Handicap" (Advanced Start only for AI-controlled civs).

Please refer to the manual (not included in the main download) and the development thread for more information. Apart from that thread, there's also a forum for feedback and discussion.

Spoiler :
Copy the unzipped AdvCiv folder into Beyond the Sword\Mods under Program Files. The path of the mod's Assets folder should then be Mods\AdvCiv\Assets. When the mod is loaded for the first time, it creates a folder My Games\Beyond the Sword\AdvCiv for the BUG settings. To uninstall AdvCiv, you may want to remove this folder (in addition to the one under Program Files).

The above assumes a BtS installation from optical disc on Windows 8 or earlier, though I understand that it works the same way with the GOG.com edition and on Windows 10 and 11. Steam users need to revert to the Game Spy version in order to run AdvCiv, and the Mods folder should be in Steamapps\Common\Sid Meier's Civilization IV Beyond the Sword\Beyond the Sword. On Unix-based systems, the mod can only be played through a compatibility layer or virtual machine. (These guides might help, but I haven't tried either of them: MacOS, Linux. These two posts also looks pertinent.)

To start the mod through a Windows shortcut, create a shortcut to Civ4BeyondSword.exe, open the shortcut's file properties, and add a space and mod=\AdvCiv to the Target field. In Steam, the mod name can supposedly be set through the launch options.

It is possible to play with more than 18 civs by replacing AdvCiv\Assets\CvGameCoreDLL.dll with this version of the file. However, doing so degrades performance a bit (i.e. makes AI turns take longer) in games with 18 or fewer civs, and the two DLLs are not savegame-compatible with each other.

A pack with more diverse artwork for units and cities can be obtained here: Ethnic Artstyles, put together by @DeepWell. (Does not support the “Animations Frozen” graphical option.)

Top Mod ever!
Excellent version
Awesome, keep up the great work! Deserves way more attention.

The manual and your well-referenced rationale for changes puts to shame professional developers.
Great mod
Very good
Amazing mod, this is the only mod you need to experience an improved, but not changed too much from the original, CIV4 experience. This is how CIV4 should have been from the start!
A love letter to any civ fanatic. An excellent way to update the AI performances and relive and have fun being a sovereign!
I've been attacked by 3 civs. While they arrive with decent sized armies they hasitate to attack. They keep destroying my improvements but that's about it. I cant do anything since they are unwilling to negotiate any peace treaty. pretty much a waste of time. What bothers me the most is that I cant get my friendly neighbors to help me (15+ diplomatic relations) but that's a problem in any civ game... Anything other in the MOD is well done.
Thanks for the feedback. I've just uploaded v0.89, which improves the AI logic for negotiating peace a little bit. From the GitHub log: "... in situations when the AI wants peace, but thinks that the human player wants peace more badly and therefore demands reparations (gold, tech, cities) ..., the AI now agrees to fewer reparations after a while if the human doesn't have enough to give." Can't say if this fixes the problem with the stalemate war in your game, but there certainly was a problem. I could look into the other issues (dogpiling, city attack courage, assistance for friends) if you happen to still have a savegame.
I do not play Civ VI anymore because of this mod.
Very good one !!
