May I remind people that EB is a mod of RTW. And that AI Diplomacy is hard coded. Meaning the team can't do anything against stupid decisions of the AI, diplomacy wise. I often play with the Romani, and several times have destroyed Epeiros completely at the start - uniting Italy, then conquering Illirya. Those times, I have allied with Makedon. Guess what they do, once Epeiros is destroyed, even though they are at war with the KH, the Getai, Pontus, whoever? They betray ME. The AI is stupid, at least diplomacy wise.

Another time, I was playing more historically with Rome, and the Koinon Hellenon suddenly decided to get Southern Italy from me. Despite the fact that they were still at war with Makedon, and that I hadn't offended them at all.


On the subject of auto-win, I don't always think of it as cheating. When facing endless stacks, I use it, because my computer takes five to ten minutes to load a battle. Hey, my laptop is 3 years old! It's hard work, even on low/medium settings.
auto_win is good, if you pace yourself. And I don't think it's required, if you use one of the various money scripts.
