i have to agree to amritochates

the diplomacy problems reported by Dayve might come from an angressive style of playing. (at least in RTR PE 1.6)
after a while even the AI offers ceasefires to me, regardless of whether i attacked them or they attacked me.
for example the gauls: they attacked me after i captured Arriminium and Arretium from rebels. I beat their invading armies in my land some times and avoid to move into their territory. after some turns, they decide not to cross the border again, and some turns further they offered me peace...even they have no other wars to fight and have plentiful units.


after all the years of rtw experience i never really figured out how the diplomacy/relationships works.
but it SEEMS to me, that the relationship in the eyes of the AI is largely based on threatening of their borders, the movement in/through their territory and whether their settlements are besieged or not.
the overall military power seems to be less important to them.
