It really depends on the game, and the type of victory condition I'm pursuing. Obviously the types of techs I need for a cultural victory are going to be different than if I'm going for a military victory, or a space race, or whatever.
This is one of the reasons I like Civ3. I can play a different sort of game each time, complete with different research paths.
