I agree with Per that the goal is to win.

But to win, a civilization may first think to survive long enough.
And does more complex algorithm (but implementable), and symmetric, could
give more fun to players ?
Could multi-part symmetric alliances, instead of the best against the
others, be more challenging for human players ? Less predictable ?
Perhaps the algorithm should be parametrised (hook functions ?) to enable
different ways to do diplomacy, as banjo said ?

I know that your current task of achieving the 2.0 is challenging, and I
hope that this little debate was fresh air.

Thank you for your time and attention,

or it could be an option that tunes the ai's level of diplomatic sloppyness,
maybe a way to change the grand strategic game by creating more unstable
alliances, unlike the long lived ones I (we?) play at present.

what happens if we put knobs on some constants to see how they change the
feel of a game.
