Do the victory conditions affect your plans?
Do the victory conditions affect how you plan your campaigns? Do you choose one of the victory conditions (military, economic or cultural) at the start and plan for that, or do you just play the campaign for a while and then see which victory condition you're closest to, or do you ignore the victory conditions? In my current campaign as Cimmeria, I just played for a while and then chose the victory condition (cultural, in this case) that I was nearest to.
