Firstly, I’m very happy to see this project progressing. Secondly, I’m very sad that I don’t have version 3.17. I’m on dial-up and I just can’t get download a patch that big, so I can’t try this out :(

I recently got Civ4 complete, which comes with BTS version 3.13. There is still one killer issue for me I’d like to fix somehow – that the AI’s don’t fight each other 99% of the time, while they happily gang up on you if you're not already dominating the world. Its really a game-breaker for me.

Even in Civ3, I remember fighting epic wars to protect my allies overseas, and actual world wars involving alliances which were not player-vs-all. Civs would wipe out other civs, and then alliances would be made against the big powers, so their empires would sometimes rise and fall in the same game. So basically no matter how many hours I invest in Civ4, it just doesn’t match my best games of Civ3, despite all the many other great improvements to the game. All because of this AI behavior.

I appreciate that most people are happy with the AI the way it is, and play only to be the biggest and best, and give up if they aren’t winning. But I’ve never played like that. I only want to play if you could come 2nd or 10th and still feel like you had a fun and interesting game.

Example: In my latest game of BTS, on the 'marathon' time setting, I fought about 10 wars from the ancient to early reneissance ages, against my two neighbours on our isolated little part of the world. I was happy just to be ‘mediocre’, playing to survive and role-play more than anything. I was even compiling screenshots, thinking of making an AAR style thing.

And then… the Byzantine Empire suddenly sailed to the other side of the world to invade my early renaissance nation with Cuirassers, Grenadiers and War Elephants, landing about 50! units in a couple of waves. I’m guessing that must have been the majority of his total military, and most of his fleet to transport it. The Byzantines used their ships to bombard my coastal cities, and proceeded inland with mixed armies including a whole load of artillery. Some of them split up, but one large army stayed concentrated and began to wipe out my last centres of resistance one by one.

On one hand, I was very impressed. I’d never seen such an invasion from an AI before, in any game, ever. It came from overseas and actually conquered my whole nation – truly a first experience for me. And I think I was only playing on ‘Noble’ level or the one above. I understand someone from this project worked on the AI for BTS, and it includes all the work you did for Warlords. My earlier wars were hard-fought as well, I could really see a difference in the AI’s handling of units and choosing when and where to fight, and I had to think hard about my own tactics and unit upgrades etc…

But on the other hand, I hated the fact that my game ended this way after all the hours put into it. Was I threatening to win the game? Nowhere close, the big players were way ahead. So was I the weakest target? Not that either, I was slowly climbing up the score ladder, and I even had my own vassal! Was I the least advanced? Not quite. Did I have major resources the AI wanted? A few luxuries, perhaps.

It just seemed ridiculous. The Byzantines could have chosen a weaker target closer to home. They could have waged a war for control of their own continent and become a true super-power. But no, they travel around the world to attack me and gain a load of inefficiently-run overseas territory just because I’m not an AI. And of course, most of the AI’s had open borders with each other, and none of them were going to take advantage of the Byzantine weakness at home after sending most of their army overseas. And I think there was only one war in the whole game between AI’s where cities actually changed hands, and that started when neither were in contact with me…

Suddenly I’m out of that immersive world and back to a rather stale, historically-themed wargame against an alliance of AI factions.

ANYWAY
, I basically just wanted to rant, but I do have some limited programming experience (made my own little games in C++/OpenGL) so I’m also naively hoping there is something relatively quick+easy that I could to on my own, in order to get the AI’s see each other as threats and targets, and/or stop treating the human player as anything special…

Or maybe there are some of your older mod versions for 3.13 lying around somewhere, that I could try? :mischief:

Thanks for reading this, and for any help/replies :)
 
This incarnation of the project (mostly, if not completely, written by jdog) is a 3.17 incarnation that started off with fixing an AI bug that led the AI to attack the most compact enemy empire, thinking it was the "closest" empire to them. (I'm not kidding)

That could actually be the reason why 3.13 AI invaded your civilization @_@.

The previous BetterAI effort was folded into BTS, and it's effectiveness (being able to invade over an ocean, for example) you can experience first-hand. :-)

Wow, that makes sense, since my nation had ended up as being almost circular after my final wars and negotiations with my neighbours, right before these epic invasions hit...

I certainly can :D I actually lied about playing right to the end... I did that today, and the Zulus ended up sending huge armies too, not just the Byzantines 50+ units. And another oveseas invader (Mali) took out my vassal seperately at the same time... If I didn't feel so unfairly victimised, I'd be singing the praises of the AI!

I also lied about no AI wars. In the replay, I noticed one overseas civ was actually wiped out early on (by those evil Byzantines) and other cities changed hands. Tho it did seem that empires were declaring war on people they couldn't reach easily, even with open borders on all fronts.

I've actually just found beyond_better_ai_v0_01.zip, which I believe fixes the distance calculation and includes the Bruhic unofficial patch for 3.13, so maybe all will be well now :)
 
Did you play with aggressive AI on? Because in my games, AI always fight among each other. There are even games where I am left in a corner building wonders, protected by my allies, where the rest of the world fight enage in a huge religious war.

No I didn't have aggressive AI on... I'll try that. What difficulty do you play on? I assume your using BTS 3.17 with the latest Better AI?
 
You took the words right out of my mouth Daft.

A little bit OT but: One of the most needed AI war improvements I think is to learn how to island hop. At the moment AI's build huge invasion stacks, even if just invading tiny islands, capture a city and leave their forces their, waiting to build up another big force until going on to the next island. They could have fought much more efficiently and cheaply (less units = less maintenaince) as well as more quickly if they could island hop effectively.

In my tests, the higher difficulty AIs tend to have the ability to produce larger armies faster, which means they can go to war more often.

A run of 1003 AD as the Incas with AI Autoplay on Chieftan and (what is the highest? Sid? Can never remember) seems to be different in this way.

On the highest difficulty, there where 3 super-empires in the entire world (consisting of a master, possibly in a perm-alliance, and (usually) nearby vassal states). Anyone not in a vassal state relationship with a super-empire ended up being dogpiled to death.
