I'm doing the Alexander the great campaing, and I'm currently playing the Megale Hellas scenario. The first battle objective is to choose an ally. I can click all the capitals to knows they're bonuses, but I don't understand how to choose my ally.
I've tried to propose an alliance through the diplomatic view, but every time I propose an alliance and send the correct ammount of ressources, the AI always reject my offer. There isn't much information in the battle objectives that could help me understand how to do it properly.
