I recommand going for a cultural win. It's the easiest, doesn't require to go to war and guides for this can be found easily.
Some basics :
- start a new game with Gandhi on warlords or Saladin on vanilla.
Why?
because spi + philo is simply the strongest combo for cultural wins.
- select chieftain level (settler is even easier but I just can't force myself to play settler. It's not a real level IMHO)
- select quick speed (normal is OK too, but epic and marathon give too much time for a late game war)
- go for meditation, polytheism, monotheism, while building warriors and settlers. settle good cottageable cities, 3 should be well placed enough to cottage spam. The rest (6 at least) are helpers, and can have overlapping with the 3 previous ones. Good production city(ies) would do you good too.
- go for agri->pottery while building workers
- go for priesthood while building workers, use workers to improve resources + build cottages around your 3 "wanabee legendary" = most cottageable cities.
-
the cottages in the 3 legendary cities' fat cross should be worked all the time to grow them to towns. So if you want to grow them by working mostly farms, the helper cities should work the cottages.
Do you know how to select which tiles are worked?
- go for BW while building the oracle in one of the 3 legendary ones, and granaries all over the place. You can start building monasteries and temples.
- when BW is in, go for writing->alphabet, start chopping the woods around the city building the oracle (if you have marble around you can make a detour to the wheel and to connect the quarry and have a bonus production for the oracle) (if you have copper around, connect it!)
- when the oracle is built, select theology.
At this point you should have 4 religions + 1 wonder+alphabet.
Now, it's time to be a builder. Except that you want good defense too.
You should connect every resource in sight and start trading around for techs (even chieftain AIs will have something to give away). Don't trade polytheism or alphabet for a while.
Start building monasteries then missionaries all over the place. You can select a state religion if your most immediate neighbours have the same one and you can select it too.
If it's not so, just send one buddhist missionary to every immediate neighbour (you need to open borders) and one hindu/jew/christian missionary to other neighbours.
It's time to go for drama->litterature->music, while continuing to cottage / road / improve resources and building missionaries/temples all over the place (don't forget to have 2 axes per city, a few spears may be good too if you managed to trade for hunting).
When you have drama, start building theatres in at least 6 cities, including the 3 big ones.
When you have litterature, build the national epic in your best GP farm site. I like it to be one of the legendary ones, but it's not necessary. This GP farm requires a theatre, then the globe theater and will work food tiles (seafood, food resources, farms) while running artist specialists.
You can start building the great library. It's best built in one of the 3 wanabee legendary, but not in the GP farm. You want 1 GS, not 2

.
When you have music, settle the artist in one of your wanabee legendary + holy cities. You should get a prophet soon, build the shrine for the most common religion in this city.
When you have the great library and music, you can trade every tech you want. Time to backfill.
good techs to get : mathematics, currency, sailing, IW, monarchy.
Now it's time to go for liberalism :
tech to CoL (you may get confucianism) while building those theatres (the rest can still be building missionaries, monasteries, temples as neede : you want a temple for each religion in every city. Priority to the 3 big ones.
When the 6 theatres are built you can start globe theater in the GP farm.
When you get a GS you lightbulb philosophy.
Meanwhile you tech towards paper->education.
If you have not used enough artists in the gp farm, you will have a second GS. Use it for an academy in a legendary city.
You can trade paper or philo, but not both. Don't trade education. build courthouses everywhere except capital. I didn't mention it, but your 3 big ones can build libraries, and you need at least 6 of those.
As soon as you have philo and education you start teching towards liberalism. Start building universities. When you have enough of those, build oxford in your great library city.
When you're 2 turns away from liberalism, trade away. You want to tech as high as possible now.
You can trade education if needed, noone will beat you to liberalism now.
You should have monarchy now (trade). If you managed to trade for CS, you will choose nationalism as free tech. If you didn't you will choose Divine Right, giving you one more religion

.
Now you switch to free speech and free religion, set research to 0%, the 3 wanabee legendary start working as many cottages as possible, you push the slider towards culture as high as possible without running out of money.
Build market (and grocer, and bank if available) in your shrine city. to increase this, build markets in helper cities and run merchants to increase this. Build wealth in your helper cities to increase this.
Your 3 wanabee legendary continue to build all culture buildings available (including hermitage in the "second best"). Priority to cathedral at this point.
The artists you get from your GP farm should be stacked and counted.
When you have enough of them to bring your 3 big ones to legendary at once, you use them as culture bomb.
Et voilà.
