Have you checked whether the AI is aware of the Atreides' desert-farming-bonus? (Basically: Do they build farms on desert tiles or not?)

This should be fixed in 1.1.2.
In the previous version AI would only consider how close a potential target is from the center of their army.
In 1.1.2 they should now first look at targets closer to their biggest city and only if none are closer to their city will look at targets near their army.

If the human player gives himself the same resource-advantage as the high difficulty-levels provide to the AI, he can just do the same thing.

Made some progress on AI unit-composition and economy-management.

This is what the highest-difficulty now looks like to me.
Take into consideration that this is turn 66.

Definitely not unit-capped anymore!

Your theory for 1) is incorrect. The true reason is the following: The AI runs several cycles and in each cycle they consider all possible options. Using abilities, moving somewhere, attacking something and healing (including retreating when they are threatened). Now the problem is that when they ha...

When looking at that screenshot, I might want to take a look at how my changes impacted tech-selection. I was not really aware but it seems like a lot of unit-types, especially heros, were skipped. The scores for those probably still scale with the amount of existing units in that category. So a sim...

In my local build issues 2) and 3) are fixed. Issue 5) should be a lot rarer aswell. Those three issues were all intertwined and while there's still a lot of potential for improvement, it's looking somewhat good in the economy-management department. I'll revisit it once the other issues start lookin...

I now know the reasons for that but the solution is not as simple as one might think. I think the mechanisms behind deciding if and what to build should be changed on a rather fundamental level. It goes pretty deeply because the whole resource-management is linked to it and just changing one thing c...

Well... the things you tried to use were correct. Their weakness are units with high-armor and high single-target-damage so using Leman Russ and Heavy Weapon-Squads was correct. Also both units can outrange them. I guess you just didn't have enough. HW-squads should be the more cost-efficient unit i...

It might be space-marine-specific.

The Orc and Necron were still happily building everywhere. The space-marines, once again built nothing after the end.
And this time they even placed 4 Fortresses at the same location.

20180818102627_1.jpg Seen after clicking Play more turns after losing the game. The green AI (Space-Marine) doesn't build anything in their city despite having a lot of resources and absolutely no plausible reason for it's behavior. They still move their untis. Another thing to maybe look into is w...

How are difficulty-levels above Impossible supposed to work?

As far as I know there's a hard-cap ingame that makes Loyalty above 50 work as if it was 50. So it only shall add slightly loyalty by not letting it drop below.

I agree that as of now for a somewhat experienced player who know's what they are doing, the default-game-mode, FFA, is basically unloseable regardless of difficulty because of the many shortcomings of the AI. It didn't seem so bad when I first started but the more I know about the game the worse th...

I just almost killed my own Monolith when firing while it was under the impact of "Get's Hot". Currently the only way to figure out that you have this curse is to hover over the weapon-icon and see the debuff. When you didn't notice being cursed, this might very easily slip your attention....

For units with different spells suited to deal with different types of enemies it can be a pain to compare the damage preview of all the spells. For example for a C'Than you have 3 spells and the normal attack (when in range) to compare. This requires a lot of time and clicking. Basically 6 clicks j...

I joined an ongoing multiplayer-game to replace an AI. But I then had the issue that my turn was always considered finished as soon as I moved my first unit. And while I could still order my units around and select things to build, I would not get any reminders and would have to keep track of everyt...

I've read about this before on the steam-forums but I've never seen it directly reported as a bug. Also I needed to make sure it is actually the case by testing it myself as I didn't want to make an unfounded claim. I tested with Astra-Militarum and the "Inspired Training"-Edict. Cost of a...

When you start a new game without closing and reopening the game and want to research your first tech, the research is still scrolled to the tier where you were in the game before.

Luckily that issue only lasted 2 turns after that it fixed itseld.

But on the bad side: the game later crashed for the host so it was gameover for everyone.
