We have finally reached the point where I am ready to share the larger map and the new civilizations that come with it. You can get them by updating to the latest develop branch.

Along with the map and civilization changes, a lot of other things have changed. Even though I usually mentioned them somewhere in this forum at the time, I will include a (best effort) full summary of everything that changed in this post.

You can find a full list of all civilizations in the game as of 1.18 here.

Feel free to play the game in whichever way you like. Since I have been very adamant before about access to the map branch and how to interact with it, I want to explicitly say that nothing is off limits. You can play and post about it in any way. However, I would still like to ask not to create modmods based on the 1.18 development branch until it has been fully released.

Please share your experiences in this forum - you can use the general discussion thread or start new threads as needed. Please be aware that development is not yet complete and do not report issues for parts of the mod that I had no time to work on yet. That includes for example city names, great people names, dawn of man texts, civilopedia texts, and similar flavour content. You can find details on what I have yet to work on in the "Updated Plans for DoC 1.18" thread.

I especially welcome all feedback on game balance, UHV challenge, AI competitiveness, tech balance, and usefulness of the new game assets like UUs, UBs, and UPs. Of course, please also report any bugs and similar issues you encounter in the bug reports thread. To be clear, you can use the general purpose DoC threads in this context. 1.18 and the big map are the default mode of DoC from this point on.

I will move on with the remaining tasks for 1.18 according to the laid out plan, but I will also do my best to engage with the discussion in the forum here. I also plan to revive the "Leoreth Plays..." series for the civilizations added in 1.18, so be on the lookout for that.

I hope you have fun!

Hooray! I know how I'm going to spend my weekend! 🥳
 
This is awesome! I have a piano lesson tomorrow that I am nowhere near prepared for. Oh, well, I've prepared for all of the other ones this year. Hope my teacher is understanding :)
 
A little confused. I deleted and reinstalled. I went and loaded the mod and clicked play now and the map looks different but it is the same size, civilizations and leaders. If I go to play a scenario then quick save it shows me some of the new civilizations but no option for which year to start. When I launched the game I get a series of error messages and then a you have been defeated screen.

I've got a similar issue. I Zip Downloaded the develop branch and loaded into the map and everyone spawned in strange positions of where they were supposed to. I checked my folders and they are missing maps for the new civs and the new resources are missing. It's been years since I used Git but the files on the git develop branch are missing the same ones (i.e. new map, Civ territory png). It could be an permission thing, the map branch was locked before, or very likely I'm not using Git correctly.

I'm not sure if this is a bug, but should the Celts really have an empire this developed at Rome's spawn? They've only been around a few turns. Also, barbs conquered Athens and Magna Graecia is now just Graecia in general. I've run a few regent difficulty/epic length Rome start a few times now and this situation seems common.

I'm not sure, but as an Irishman, I love to see it.

So far, I'm really loving the new map, halfway through a Celts game. I conquered some Carthaginian city in Spain (which autorazed for having 1 pop) and Athens (which I kept). I also added in the Cape art that I had mentioned in that other thread a couple of weeks ago and I think it looks great (Screenshot attached).

One thing I noticed is that Assyria doesn't have diplomusic, I suggest using this audio file (which was the early Middle East peace diplomusic in Civ 3)


Overall, I think the map is great, nicely done Leoreth, Bautos42, and everyone else who contributed to the map.

I noticed some issues with city naming. For example, Egypt's first city is called Akhetaten. Also in the 1700 AD scenario Ottoman cities have either their ancient names or their Greek ones.

How do you update to the 1.18 development branch?
Simply get the latest develop branch, there is no difference to before.

STABILITY
  • Capital city grants non-scaling additional stability limit
Can you explain what this means?
Every city in the core adds to the expansion stability limit, and then that limit scales with the game era. The change here is that the capital additionally adds to the limit, but that addition does not scale with the game era. In effect it means that there is a bit more room before you get negative expansion strategy, but that effect becomes negligible with large cores and after the classical era.

You're right, something happened here. This was not my experience when balancing the ancient era but that has been a while ago, because I did that part first. It seems some other change has impacted the Celtic performance somehow, I will investigate.
 
A downloadable installer will only become available when the 1.18 release is created, i.e. when work is completed. In the meantime, as usual, it is only accessible via git.

Should be fixed with the recent update - I think it was a side effect of the merge with the develop branch that I missed.
 
When you say getting it is the same as before, not sure what you mean. I uninstalled then reinstalled the mod but not seeing how to get the development branch for 1.18. Excited to spend the weekend playing this just gotta figure out how to get it working first lol.
