Quick question about Defeat/Death screens

It's the same as for the minors... But majors often surrender before getting totally wiped out so you'll see it less often but still enough that I am worried why you think there's no sequence for them. Maybe you thought it's a major, when it was a minor?

I took out the Torians by military rush in my current game. I forgot to turn off the Cult rating and I didn't want them to hand themselves over to anyone else. I took their last three planets and that was that. I was kinda getting kinda curious when I didn't get a defeat/death screen, I thought that I may have missed one of their planets.

Should you also get the defeat/death screen when you "flip" that last of their planets?

No, I think only when you conquer em...

Not only that, you can take the AI's last planet, and then STILL trade with them. I take the AI's last planet, and then sell them all my trade goods and tech for as much BC as possible, getting a 50 year lease so I extract the maximum. I also throw in a peace treaty for a few hundred extra.

Not only that, you can sell them back a planet, to keep them from being eliminated. (Doesn't matter, because the planet will culture flip back to you in a few turns anyway.)

It doesn't work with minors, though. It works with any major, whether it was an invasion or a culture flip.

That's an interesting idea. I should try that on my next game.
