I-League and Culture

Yes, they basically are immune to culture. As you found out, you can have thousands of points on them and they don't sweat. If they are a problem, work around them or take them out. But, they can also be lucrative trade partners.

Any race can lose planets to culture, but most, if not all, minor races have an inherent influence resist. Note also that the near-major races have cuture ratings of their own that can get pretty significant. I've taken I-League planets by culture before, but it's not a common event, and I've probably lost more to their culture than I've taken from them.

Well, I added a few attachments to my uber culture starbase in their sector. I guess they got *so* excited about joining my empire that their whole solar system just popped when my now death star came to say hello. Honest, I didn't blast them for being the rebel scum they are...honest!
