Hello,
Please forgive me if this is a Noobish question, but I read the manual and I watched the tutorials and I can't find anywhere a reference regarding the conditions needed for forming an alliance with another Civ. I researched the Alliance technology and it doesn't appear as an option on any of the negotiation screens.
I have warm->Friendly relations with all other civs. I imagine it needs to be even more friendly before this is an option, but is that the only requirment? Also, whats the best way to improve this? I have gifted techs, money and influence to the Altarins for instance, and after the gift they will get as close as friendly, but then the following turn they will suddenly drop to neutral. It seems logical that continued gifts as well as increased trade will influence this, but there is no way to know in the documentation or through the tutorials.
Thank you for any information/advice/assitance!
