Okay after realizing that what I thought was an emperor win was in fact a monarch (arraaarrgh), I started again, this time with Saladin. What I wanted to try was to grab Buddhism and Hinduism, then wait for a great religious leader to get Code of laws, and then pursue to drama, liberalism, switch to 100% culture and focus on great artists, and see what happens.
I chose peaceful civs, without the industrial trait or the spiritual one to give me a headstart for the early religions : Washington, Cyrus, Victoria.
The first thing I noticed is that you want to be alone on your continent. If not, the best spots are going to get settled really fast.
My opening move was Meditation, Polytheism, Priesthood, then Mining and bronzeworking.
My first city prod was warrior or obelisk, then Monastery once I had meditation, then temple once I got priesthood to start the great Religious leader, then worker. I'm not sure if this is a good idea, but if you want an early religious leader then it's the best thing to do, because Saladin does nto have any useful techs for an early worker, and if you go for bronze working first you will get beaten to the early religions.
Anyhow I got Buddhism and Hinduism, then a great leader, then Code of laws.
I founded three cities only, and one of them got judaism so I had a fourth religion to build temples, monasteries and cathedrals.
Everything basically went pretty well right up to the point where I discovered philosophy. I decided to switch to 100% culture and wait for liberalism to be more accessible.
But the thing is, having only religious buildings, librairies and theaters is a bit light to get an fast cultural win.
That, and having the religious wonders is actually a bummer because if you get unlucky (like I did), you can get 6 religious leaders in a row even with 5 artists in the city ! I had a 25% chance of popping a religious leader, and I got it 6 times in a row. Not good
But it would'nt have made any difference anyway, since by the time Washington won with a SS victory in the mid 1800s in was only in the 25,000 culture point per city.
So I don't think a purely peaceful strategy is going to work for that gauntlet. You not only have to get lucky on the great artists (or maybe try not founding any religions so as to get only great artists points in your cities but I'm afraid that will only make matters worse because then your religious cultural buildings will come to late if you wait for your neighbours to convert you), but you've got to cripple the AI.
It's too bad, because from what Firaxis said I was under the impression that a peaceful strategy would be viable on the higher level, but apparently you'll have to do some kicking...
Anyone tried something else ?
