I just tried playing a game with random leader personalites.
I got a Magnanimous Yang, and and an Aggressive 'Seek, Kill, Destroy' Zacharov. I had over 1000 every credits, several more techs, and Zach simply landed on my Island with loads of Impact, and later Gatling infantry, instant vendetta with no option to buy peace, and easilly rofflestomped my synthmetal defenders
... Now how the heck can I make AI Zach play like that all the time? He was far stronger than Miriam or Yang ever could be with his military tech lead.
