cultural bombard the AI
End of quote
I haven't quite figured this one out yet as to how to swing them culturally.
The first game, I was quite happy with the alliance victory. I had a horrible starting position (I always play what comes up) with just two planets in the top northwestern corner and nowhere else to go. I went mostly research and trade at that point.
The second game was also close. The Arceans were to my north and east and had grabbed some stuff near me. I almost lost one planet to them to cultural pressure, but I staved it off. I helped them against the Drengin. I traded with them and got some combat transports which I promptly parked around the Drengin planets. As the Arceans or I cleared the defenses I was able to get about half the planets.
It was funny in the second game as the Drengin were demanding tribute about every other turn later in the game. Then I got the message that the Arceans were going to war with the Drengin, so I joined in
The Arceans were quite strong near the end. I could have probably pulled off a conquest, but I don't mind the alliance win. I leave all the victory conditions on as to me a win is a win. I would rather have the option, as in the first game, to at least go for an alliance victory as the starting postition was horrible.
