Sulla's Civ4 Walkthrough uses Saladin. So did
GOTM 7. You might find some tips there...
Quick (and abbreviated) list of some things you can do (some simpler than others):
* found Hinduism, build Stonehenge or Oracle, build Hindu shrine, build missionaries, try to convert AIs, eventually build Wall Street in city with shrine
* settle a city with high food, run Caste System, run many scientists in that city, get a lot of great scientists
* temporarily switch religions and civics to placate AI and/or get temporary diplomatic bonus to get them to do something for you.
* get fancy with rapidly switching civics: switch to military civics and have all cities build military units, then switch to Organized Religion and have all cities build buildings, etc.
* build Pyramids and run a "specialist economy".
* get a cultural victory based on artist specialists. Build the Pyramids (then run Representation for increased science, or Hereditary Rule if you need more artists in your 3 culture cities, and Universal Suffrage to cash-rush cathedral buildings) and/or the Sistine Chapel if possible.
