Could it depend on which race you are talking to?
I have 1 or 2 races that just will not communicate with me.
But I have 1 race that is almost destroyed that when I ask to surrender tells me to "stop bothering them".

The AI's always finicky. If they're refusing to surrender, wipe out the majority (75% should do) and then use troops to capture their homeworld. If they don't surrender at that point, then sucks to be them. Wipe 'em out.

In SEIV the AI would surrender when your score was 10x theirs. I haven't figured out the threshhold in SEV - because none of the buggers will surrender to me

...one or two planets before they surrender.

Every now and then I get lucky and they surrender earlier... to me even.

So that was the score threshold? Interesting. I used the aforementioned technique of obliterating colonies and then capturing their HW using troops. It was a pretty bloody fight and was against a neutral, so not as tough as capturing an entire empire, but I'll be damned if they weren't persistant in their refusal.

I once forced another (normal) AI to surrender that way also.

IN UR BASE KILLING UR DOODZ

works every time.

There are 2 kinds of AI races in SEIV and V.

Main AI (Cue Cappa, etc) and Minor races. The minor races never leave their home systems and they all use the same shipset. If you click on their race in the Diplomacy screen, look at the picture of the ship set. If its the generic shipset, they are a minor race.

There appears to be a bug in SE5, the minor races do not communicate at all.
