How to get a high score?

[Skallagrimson]

When I realized they were never going to by my buddy I stopped caving to demands and let them invade. Since everyone who bordered me was pleased/friendly and I was out teching everyone and rich I would just bribe them into declaring on whoever declared on me and not a single enemy unit ever entered my borders until my own allies suddenly declared on me in the last few turns of the game. Is this about the best I could of managed this since I couldn't get the majority religion in any of my towns?

Even a best buddy will not be able to resist the tempation to invade you if you're militarily weak. But if for most of the game you can keep invasions at bay and the diplo scenario is such that all your neighbors are important allies, that's a factor in favor of going for culture victory there. Or space.

Representation only affects specialists, not great people(I think)

GP production is boosted indirectly because with the 3 beaker bonus for each specialist, you'll be running more specialists. Even an artist starts to make sense...
