Ok, can do a bit more.

Game1
Build is soldier, scout thopter, worker, water cache, settler, barracks.
There is a non-trivial diference in AI performance I think depending on whether the 3-mesa chain at the capital gets 2 windtraps or 1 (ie do they build windtrap on the center tile first, or on an end one).
They build a 2nd settler for a 3rd city pretty soon too.
By turn 100 they are in first place, and have a 3rd settler built.
I have no idea why Roma is expanding so much more and faster. She doesn't have an Expansive trait or flavor.
Ai found Imperium religion. This will be a big help, diplomacy-wise.
By turn 150, down to 4th/5th place. Partly because the 4th city is built 1 SE of the nitrates, which removes the windtrap from the capital's BFC, so it stops growing and starves down to size 5.
1 Saboteur by turn 150 (just discovered law of arrakis).
Fallen to 6th place by turn 175 (but 2nd through 8th place are all score 1200-1400).
Again because of poor city placement, lack of expansion. One of the places (island to the east) where the AI normally expanded had a barbarian city spawn there, that was captured by Corrino.
3 saboteurs, but very low EP income.
6th place by turn 200.
4 saboteurs, but barely enough EPs to use any missions. Prison camps just being constructed.
Saboteurs don't really seem to be going anywhere.
Again observe lots of cities buildign wealth, getting up gold to upgrade units.
This is quite inefficient. IIRC, building wealth = 2 hammers per gold. Upgrading units = 2 gold per hammer.
So, building Wealth to upgrade units costs 4x as much as it would be to just disband the units and build new ones.
I'm not sure how we should fix this.
Saboteurs *are* traveling around in Corrino territory.
Fremen invade, and destroy a lot of units and pillage some stuff, but don't take any cities.
[Aside: Fremen Raider should be renamed Raider; otherwise the game refers to them as a Fremen Fremen Raider. Also, I'd make them strength 10, 30% withdraw chance, melee unit. And maybe move them to a different tech.]
Turn 250
Down to 7th place, thanks to the Fremen war.
Saboteurs aren't in Fremen territory, they're still generally wandering the deserts.
I wonder if they're constantly changing their mind about what mission to carry out, and changing direction?
250-1000 EPs accumulated against each other player.
6 Saboteurs, all generally sitting around. All fully promoted, but do the promotions do anything much?
500 EPs against Rabban.
So, espionage is pretty useless. We need to drastically improve the AI somehow, and maybe make some of the minor missions cheaper (eg improvement destruction) or more effective (eg poison water for Tleilaxu)
