Allied victory conditions?

[ccarollo]

I'm about to start an allied game with friends (2 on 2 on 2), and I want to be clear about the victory conditions in this kind of game so I can develop a strategy.

Do victory conditions span both me and my teammate's civs? For example, for the population/land area victory condition, is it both our civs combined? For the culture victory, can he have 1 city with 50k culture and I have 2, or does one of us have to have all three?

Also, do the civ bonuses apply across the alliance? So if I took expansive, would he get +2health in all his cities too?

Thanks!

All I know, that you can lose a space race, if your "ally" starts building the engine in Palookaville, pop 100, prod 2 hammers/turn.
