Re-cap
Up to 400AD
Catherine begins with a pretty uninspiring starting terrain. She commits to an early rush while also taking a run at The Pyramids (no Industrious leaders on the map). Two extra cities are quickly founded, and Moscow is used as an Axe and Sword pump. The troops head to the south east and raze Victoria’s three cities. Victoria's dead. Two spots are soon resettled in somewhat better locations in Victoria's former stomping ground.
400AD – 1450AD
With a pretty fair chunk of land to work with, Catherine then goes through a long period of empire development. Quite technologically behind at 400AD, not only a host of Wonders are later founded through this 110 turn period, but as the empire grows its cities define and focus their respective roles. By 1450AD, Military Science is in, and Russia is five turns from Rifling. Catherine is the score leader and roughly on tech’ parity with Isabella a.k.a. Mattimeo. All nations but Egypt are Buddhist, but Spain and Celtia are at war.
It’s at this point that the variant becomes the issue;
One leader gone (already Victoria’s England)
One leader vassalised
One leader in a Defensive Pact or Permanent Alliance
Two leaders - alive, not in an alliance or vassals with the human player
I have not previously played a game with Permanent Alliances on, and am mindful of shyuhe's point, who warns that securing a PA with an unpopular vassal under your control can become very difficult (or unlikely). Furthermore, forum threads advise that there are a host of other objections that a prospective PA partner can come up with to not proceed with the Alliance, including “You are becoming too powerful for us”. The recommendation from shyuhe was to secure the PA first, then go after the vassal.
… So what happened?
From 1450AD
While merely 5 turns from Rifling and about to become the powerhouse warmonger on the Pangaea, a massive change in policy is implemented. Russia opts to court neighbouring Spain as its PA partner, and decides to bee-line Fascism (instead of Communism, thereby keeping The Great Library and The Temple of Artemis alive). Isabella a.k.a. Mattimeo helps somewhat in this pursuit through some handy trading of pre-requisite technologies. A switch to Theocracy is also part of the picture, although it would be some time before Russia would actually leverage the civic for the troop promotions.
Almost immediately into the turnset, Spain requests Russia’s aid in the war against the undeveloped yet large-ish Celtic empire.
We of course concede to the request, although are wary of Boudica becoming someone’s vassal and upsetting our diplomatic machinations. The war indeed does prove to be beneficial, as our small stack of Cuirassiers and Trebuchets that had been watching the Egyptian border to the north end up getting redirected to the west and succeed in taking two large Celtic cities before Boudica is prepared to sign away a fair old chunk of gold and gold per turn for peace. Isabella, having taken only one Celtic city fortunately too quickly negotiates peace.
More gifts to Spain and lopsided deals proceed, and Isabella a.k.a. Mattimeo finally agrees to a Defensive Pact. A PA won’t be signed until there is a considerable period of time in the Defensive Pact - an agreement that could be unstuck at any moment. With Egypt and Spain of differing faiths, there is somewhat of a Damocles Sword hanging over the plan as either could break the Pact with a moment of religious zeal.
Fascism is reached – we get our Great General – and still no luck with the Permanent Alliance. She needs to spend more time in the DP. With most other tribes now starting to make headway on the PowerChart, the opportunity opens up to review Rifling again (without wishing to be perceived as ‘too powerful’

. For the meantime Russia had been pressing ahead with developmental pursuits – long overdue city improvements, more Workers, and a few additional cities were founded in fringe spots. The Pentagon and The Statue of Liberty were added to the growing pile of Russian-owned World Wonders.
With relentless checking of the diplomatic situation, Isabella a.k.a. Mattimeo
finally agrees to the much sought after Permanent Alliance!
Russia instantly swings into troop production. Hatshepsut has gone to great lengths it would seem to avoid acquiring Gunpowder, instead off up the Democracy pathway, and apparently getting little help from her only ally in Elizabeth (who in my experience is a particularly tough tech’ trader).
It’s reported that forming a PA can mutilate the human player’s economy, however as Spain had The Mahabodhi things progressed fairly well.
With Russian war preparations underway, England's Elizabeth was lurking around in a worrysome fashion with ‘enough on her hands’ ...
... England and Celtia went to war, with Elizabeth dragging Hatshepsut into the conflict.
Hatshepsut moved her big stacks of Medieval units out of her cities and off to fight the Celts, leaving her cities garrisoned with typically three or four CG1+2 Longbows.
It was too good – we weren’t ready, but nonetheless we declared.
Catherine had to do the occasional ‘promote Axe to Infantry’ as Hatshepsut sent unexpected menacing invasion stacks to some of our more poorly protected cities, but in the end it was ‘fly swatting’.
Isabella a.k.a. Mattimeo played her part in pummelling Egyptian forces endeavouring to attack Celtic cities, but Catherine was the one cutting a swathe through the Egyptian empire. By the fall of the fifth Egyptian city, with the capital due next, we brokered the deal in 1736AD.
Overall
Following a better understanding of Permanent Alliances, my strategy underwent a significant shift in focus from turn 310 that probably led to a much later finish than I am confident is possible. I’m still unsure if a Domination win could be pulled off using a Defensive Pact instead of a Permanent Alliance, but it would require a great understanding of the mechanics of the game (triggering a win under the right conditions), or luck, or possibly even both. Diplomatic by Apostolic Palace or Cultural seem most likely for an alternative quickish win to Domination.
The variant does seem to encourage an early game rush and decimation of a neighbour, and then development as a solid but not powerful tribe to arrange the PA.
Russia was fortunate in that most tribes adopted Buddhism, and the one that went in an alternative direction (Hatshepsut’s Egypt) was essentially a pacifist.
From this singular experience with Permanent Alliances, I’m guessing that many of the religious zealots make good prospective partners (I’m thinking; Brennus, Saladin, Isabella), as you can simultaneously get diplomatic pluses from both sharing a religion and adopting a religious civic. This is one reason why I decided not to chase Elizabeth as my PA partner here.
Saved games at
1450AD (towards end of ‘developmental’ point) and
1736AD (victory triggered next turn) if anyone happens to be interested (apologies for a number of micro-management gaffes!).
