Diplomacy and Trading

[Nightblade]

As i strongly think more options are always a good thing, an option allowing or not in a SP game the diplomacy, alliance and trading possibility with the AI would be a fantastic addition to the game in my opinion.
It would even lead into another victory condition, allied victory (in the case of the game storyline, maybe that could translate into the birth of a pantheon instead of a single pretendant accessing godhood)
