Just awesome!


This mod, in many ways, is the sum culmination of all modding efforts and concepts brought forward on the CivFanatics sight for Civ4. What hasn't been done yet, they continue to work towards accomplishing. Every version is better than the last. There are miracles in streamlined processing at work that have pushed the Civ4 limitations far beyond all imaginable limits.

And let's face it... it's fun! It's by far one of the most immersive GAMES ever developed... everything the Civ franchise ever wanted to be. The vast variety of units, buildings, and features to support it all enables the player to really 'feel' every era as if he were not only there but a major player in the development of history. The depth is purely a marvel to behold.

Sure there are bugs on occasion... as a mod in a constant state of development, that's to be expected. But when bugs are reported, they are addressed with an unusual degree of attention and haste.

Perhaps the most amazing thing about this mod is the goals the design team has set for it. The current state of the game pushes the envelope as it is but from the discussions and plans being put forward on the forum, it becomes clear that the intended scope of the game is beyond the imagination.

The evolution is fascinating to witness - all the more so because for the true diehard player, they have an SVN that may be accessed that is constantly receiving updates every day from each modder on the team. And they keep all changes compatible with previous versions so you never have to lose a game you're in the middle of if you update to the next great release.

If you're not planning on losing hundreds to thousands of hours of your life immersed in strategic bliss, make sure never to download this mod!

In many ways, this is the one mod to rule them all.

Frankly, the Most Ambitious version of Civilization I've ever seen!!
Trust me, it has to be that good to keep my attention for so long.
Completely blown away by the care of the community and depth of gameplay shown in this mod. C2C redefines CIV so much that it has the momentum to set a much higher bar for Civ 6. It's already so close ; it could inspire Civ 7! You have to check out the forums and play it for more than a game or 2. It radically evolves monthly!!


Probably the best mod I've played this far, all games included.
Really amazing work !
Merci !


Great Job


A very good exteceve mod full of intence and exciteing chalanges never before seen in any other Civ Mod. Its still a bit buggy, but playable. But what do you expect from a mod created by a single, GENIOUS man. :D

Ok, I completely change my mind. I have been playing it since June of last year and I'm STILL playing it. It may be buggy, but the loads of features and such makes up for it...


I tested this MOD for a while.
It makes realy fun when you can play long parties about 10000+ rounds and even short battles.
You have evertime something to do and wehn not you make something wrong, it is never boring. The gameplay is great. It uses the strenghs of Civ IV and adds alot of new.

A bad thing by this mod is that it takes 3 minutes or more to start, but this is only a little thing. (by my first game it's also takes 15 minutes)

I wold say this is the best MOD for Civilization IV: Beyond the Sword


1st things 1st, new version 38 will be released soon. Again so many changes since v37.

The later Eras are getting much attention and are fleshing out. (Spoiler: No multi maps this version, sorry.) The Mod Team has spent a lot of time on balance this pre 38 time frame. The Property system for Crime, Disease, Air and Water Pollution, and somewhat for Flammability has been really picking up momentum. All Units, Buildings, and Techs have went thru a Re-Costing project. So that they all scale as the Eras go by.

Game Speeds have been re-worked with the eye towards balance for Each Game Speed's tendencies. The slowest Game Speed Normal is 1000 turns, Epic is 2000, Marathon is 3350 turns, Snail is 5035 turns, Eons is 6550 turns and Eternity is now 8250 turns.

The number of Game set up Options has increased as well. Much more customization given to the player.

Subdued Animals, Barbarians, and the Neanderthal NPCs have their own AI's now, and their own options. There is also a Neanderthal Leader and Civ that can be Human played. But there are still 5 total Non Player AI's, 3 Animal, Barbarian, and Neanderthal Barbarian.

The late game Eras have been revamped as well, and expanded. After Modern Era, you now have Information, Nanotech, Transhuman, Galactic, Cosmos, Transcendent, and Future Eras.

Game play is consistently allowing you to get to these later Era, if you choose to. Or you can go all ballistic and war monger from the get go.

For those more Combat minded there are also new expansions to the Combat Mod Options you can select at mod game set up. Or if you want a more base Civ IV BtS feel don't select them. The choice is always yours.

Leader Traits also give you multiple options on how to use them. From None at all, to Positive only, to a mix of positive and negative,and to an option for leaders to develop their traits as you play (Developing Leaders).

So Much to choose from.

And for the Uber players we are working on making the Mod much more difficult. Such Options as, No Tech Handicap for human player coupled with Tech Diffusion and Win for Losing On (for the AI) allows the AI to learn new techs easier from their neighbors.

I've just touched lightly on some of the areas that have been worked on over the past year plus since v37 official release.

Now finally, why do I only give it a 9? Because it's still a Work In Progress. The Team knows there are still areas to work on to make it even better and Projects are being formed for post v38 release. The team also knows that a mod this complicated and big, even with the dedicated players we have, will still have some "bugs" show up. Finally it is after all a 32 bit single thread engine that runs Civ IV BtS. So there is that limitation to initial game start time and as the game progresses end of turn processing wait time. This is Not a Modern day game that can use Multiple cores. It has a limited amount of memory it can use (~3.5GB). And CPU speed is more important than having 16 gazillion GBs of ram in your comp. A decent but not ultra vid card does help somewhat. But don't forget this is a single core engine that runs this MOD. And all our Graphics work is from volunteers and fellow CFC modders, whom we the team are forever grateful to.

Best Mod Ever! :D

This mod is nothing short of mind blowing. One of the most ambitious and well executed mods I've ever played. The team behind it is just as brilliant as the content within it. It takes everything you loved about Civilization IV and expands it, while building upon concepts that made it so great. As a starting tribe(you have to work a bit to even be a civilization), you need to hunt for food and fight off your primal cousins, all the while trying to evolve. This is but a few of the many concepts introduced in this mod. So, can you do it? Can you build a civilization that can truly stand the test of time in what in my opinion is one of the greatest mods of all time? Download and find out.


Great mod , kept me for hours.
