Strategy: A Haunting Tundra Melody

Early on, tech Pottery absolutely first and try to snag the first pantheon. Take the pantheon that will yield the most faith, even if it's only a little. Shrines should be prioritized highly in order to get the faith rolling. Teching mining fairly early to get the Yellowknife encampment is also a good idea, but don't neglect lux techs or Philosophy. Try to secure as much Tundra land as early as possible, and when choosing beliefs, pick ones that will give the most faith yield. Make sure that cities grow fairly large, since you'll need the citizens to work the Holy Sites and Yellowknifes in order to take full advantage of them. Between buildings, make sure to put the iron to good work by building a defensive army, since the Holy Sites and religious pressure will aggravate neighbors.Mid-game, try and work Musician slots before the others, since the musicians also improve faith yield in addition to the tourism from Great Works of Music. Opera Houses will have to wait to be filled, since the bonus faith is more immediately useful. By now, Sacred Drummers should be slowing down, so one might consider sending out Missionaries if they haven't already to secure a large religious buffer zone. With the Holy Sites producing Tourism and the musicians doing so as well, some of the weaker culture civs should be experiencing some issues. Dipping Patronage for the Forbidden Palace will help World Religion pass, increasing the power of your faith. But as for a main policy, Aethetics will boost musician generation, as well as the tourism yields.Late game, culture victory should be coming closer. Freedom is probably the best ideology to take, as it will allow the New Deal tenet to improve the already powerful Holy Sites. Having Radio Towers in all cities will increase tourism, and will yield more music slots to boot. Always mantain a standing army, since people will begin arming when they fear your victory is near. The bonus to tourism from religion should be helping the end touches, and using a few musicians for tourism isn't the worst plan, especially if there are no more shrine or temple slots. Eventually, all the world will know the tune of the drums echoing forth the memories of your grand people.
