Finally, I have a little time to write a report about the build 3. I already reported about the Britons game progress to
Guardian, so now I may report to all who waits.
I started a game as Britania, my neighbors are picts to the north, gauls to the south through the Dover strait.
My strategy for the game:
1) no neighbors on my island to consume my resources;
2) continental landing and development;
3) cajole gauls & teutonarii;
4) capture Massilia;
5) challenge the Rome.
OK, game is started with 2 cities each civ. And here, at the very start, there is a weakness point in the AI play - it started to build wonders. Picts started to build Barbarism - its effect is (+50% strength vs barbarians) and (+1 culture), I may start a Stonehenge... And this is 1st weak point of the AI play - while Picts build their pretty useless Barbarism, I build cities to boost science/economy/production and, what's most important, troops!
Finally, Picts completed Barbarism having 2 cities and 4 archers (defenders).
I have no Stonehenge (well, it's not a big problem), but have 7 cities and 2 copper fists: 4+4 & 3+3 spearmen and swordsmen. These are next to the archer generation of troops. This is a basis for task (1) completion... And it is completed pretty quickly - Picts built 2 more cities, but anyway I took them all. Task (1) is done.
Building more cities, I reached a tech which gave me boats. A basis for task (2) completion. But suddenly I understand my boats can't transport my settlers... Ugh. So it won't be a peaceful landing but a military campaign. OK. I need a couple of cities to start building settlers. And one more bad news - I can't settle Ireland.
One more bug - phantom resource bug. I even tried to start to build Alexander The Great Army, a national wonder of Greeks - I had a Macedonia resource.
I transported 8 spearmen, 6 swordsmen & 2 slingers-mercenaries (invisible, 2 moves, weaker than swordsman), met Gauls. I traded contacts to Gauls & Teutonarii (and everybody is annoyed with me - this is their problem, I'm safe on my island), gave a gift to Teutonarii not to disturb me while I'm at war with Gauls and, as expected, declared war to Gauls (they closer to my territory - easier reinforcement). Capturing 2 coastal cities (one of them close to the Lutetia, 15 pop, 2nd important city for Gauls), I met resistance of invisible (and average) mercenaries only - AI chooses to build only them. Since Gauls had only 6 cities (and I'm 15+), they accepted peace.
I started to build settlers in continental cities (I need more cities!) and reinforce my troops from Britania island. Suddenly, Gauls declared a war on me! That was unexpected, and the more unexpected was to see their galley moved to the island - I moved big part of troops to the continent... So, Gauls captured 1 of my undeveloped yet cities, but I retook it quickly enough using horsemen - I already unlocked an appropriate tech.
Being at war with Gauls, I captured 3 cities more (and of course Lutetia, which was so important), signed peace and took 100 gold from them. Since there's more income than outcome, so I don't afraid about the treasury, and theirs too. Task (2) is completed.
Being at peace, I started to build coastal cities to the west to avoid a border to Teutonarii. Next step is to go to Massilia, and I prepared 16+16 spears & swords, 4 slingers & 8 horsemen. That time I stopped for now because of the technical reason.
Technical reason is the game works very slow. In my own mod I have the same size map, around the same number of cities it works much quicker. So I gave up to wait for 2+ minutes turns and stopped. I have powerful enough PC and experienced no problems with other mods, or, at least, I saw the reason - full of cities and units map. But this situation looks a bit strange, this is an object to investigate.
From my story you may notice there's no historical accuracy in my doings. I asked
Guardian about it and he answered "predictability is boring". I told another point of view - if player wants UNpredictability, let them play
CCM or
Worldwide. So this scenario is not historically accurate right now, and it's not about the Roman history - oppose to the
RFRE

. The scenario is about Civ3 gameplay on the huge Europe map under Ancient era conditions. This how it is.
So, the next and big my question to
Guardian was to decide whether the scenario should be "historically correct" but predictable, or just a gameplay (Picts & Gauls destroyed by evil Britons). I have no answer (I don't hurry, it's a hard choice) yet.
So, this is how it goes.
Summing up bugs:
1) wonders - slows AI development, pretty useless (see my Barbarism description), "nationalized" (no challenge in building them).
Suggestion:
- make wonders more powerful (+20k, city radius 3 in 5 turns -> resources);
- make them "cultural-depended" so it won't be good for human player not to build them.
2) mercenaries are preferred by AI and it doesn't build any other units except them, even they're average units.
Suggestion:
- using of autoproduction. Autoproductive building should be the small wonder.
3) slow working.
Suggestion:
- find and fix a reason.
4) historical inaccuracy.
Suggestion:
- to decide whether it's a worship to the (Rome and Civ3) or to the (Civ3 and, probably, Rome).
Please, feel free to ask additional questions.
I'm very short on time this period, but I'll try to answer to all.
Thanks!
PS One more note: map is too big, so there'll be almost impossible to capture all "historically correct" territory belonged to the Rome. In
RFRE it was difficult - but it was a challenge.
