How to get AI EMpire to Surrender !?

[Arkcon]

It's already been said that some TDM Modpack Ai's never surrender. In at least some of those cases, I think their speech files have been edited to not contain a surrender dialog, you you might want to check that.

At any rate, you have to be far ahead of them to get a surrender, so here's a plan. Bloackade their Last remaining planet. If you accidentally glass it, demand their surrender, they may do it as their Last turn goes. Also if the planet riots, then rebels, you get a new AI generated, they'll be more amiable, cause they'll use an SE4 default AI.

Here's something else, early in the game, generally, it's a waste of research points to research colonization yourself. But if you've beaten an AI, you've invaded or colonized a lot of prime planets, maybe you should research the other colonization types yourself.

Consider your other AI opponents, if you gave them a bonus, they may already have all colonization tech. It's unlikely they stole it (they can get it via surrender too, not any other way). And they're flying around, snapping up ruins planets and huge breathables ...
