From post #17:
The best starting techs are Agriculture and Hunting. This way, for MANY starts, you can research Animal Husbandry at a maximum discount (AH resources are common and horses are great for the early game) and then research Archery immediately after if necessary for barbarian defense. This is why I like starting out as Persia. If you've got a coastal capital, then you can just research fishing before AH and then archery after AH if necessary.
I forgot about scouts, though. They're nice if playing with huts on. And furs and deers can be used with hunting.
