how consistent is the diplomatic AI ?

[Mr. Juice]

Pontus and I (Scipii) have been pals for more than 50 years now. After playing M:TW, I am still in complete disbelief. An ally that acts like an ally!

In my first game, a Julii campaign just for the sake of messing about. The Gauls were my main diplomatic contacts; I asked them for a ceasefire because although I was beating them in the field I desperately needed to sort my negative cashflow and reinforce my troops. The Gauls agreed, they even paid tribute of 2600. On a whim I asked for an alliance; it was accepted. Next turn they broke the alliance. I repeated this process, with around the same amounts of cash each time, every turn for something like 6 turns. My finances were so bad even the huge tributes left me with a negative each turn.

Now I am doing a Brutii short campaign with more serious intentions. This time everything is going quite well, but diplomacy remains ... odd. I allied with the Macedonians; it lasted for maybe 3 turns before they marched an army in and started attacking my cities. I then forged a peace and alliance with the beleagured Greeks to take on Macedon. It lasted one turn.

My Roman allies have been very good, declaring war and ceasefires to match my own dealings, also sending armies to protect my cities from rampaging rebels.

froggy conclusion: non-Roman alliances aren't worth the paper they are written on. The Roman alliances are great, everything I had hoped for.

Agreed. In my currect Julii campaign the Senate sent a full stack to kill off a stack with two rebel units However, the rebels seem to manage to escape or retreat from the senate's army each time so there both just moving through my territory for some 5 turns now... Something I liked: the Senate asked me to send an army to help them surrounding this rebel army. So far my pathfinding has been so lousy that I didn't succeed yet

Got some hard cash from the Gauls now for 2 turns (2 x 1900 denarii) which was invested in city upgrades and recruitment. And now I am about to break the alliance as the senate wants me to capture Narbonensis.
I like this game.

Don't know if this counts as a diplomatic matter poroperly, but on my current campaign as the Julii I've seen repeated occasions when a Roman faction will make peace with another lie Carthage or the Greek Cities and then the next turn be at war with them again. It's happening repeatedly, so either it's a slight bug or everyone's a flithy traitor, in which case it is very consistent.
