low approval wouldn't make them rebel, that's only controlled by influence levels.

Nuke 'em till they glow! That's what I'd do.

Wins by influence are for wimps!

(just kidding--I'll go for an influence win any day)

I doubt relations could be much below friendly, or would be if the war was called off for a couple months. An alliance victory is also possible.

hey, aren't the Korx notorious for selling their own mothers? in other words, they would flip over to you in no time (compared to other civs) should you press the right switches...

oo, yeah, nice idea, let it get out of colntrol (pop stops growing at 40%, reverses at, 20% i think) then use information warfae, like the person above said.

"(they kept petitioning for a treaty, but they started the war)"

Been there, done that . Most AIs in this style of game think they can push me around because they have a big military - and often I have a smaller one because I focus on economics. Then, when they declare war, I turn every planet into a war machine and proceed to show them who really has the larger military capacity. Usually, because of my focus on techs and economics, I actually have a larger capacity to support the war even if I haven't built very many ships yet.

The same thing happens when I play one of the Civ games - the AI thinks I'm weak and puny because I have no military, but they fail to realize I have the economy to support building units in most cities every turn. Usually, this results in the other civilization disappearing from the map, unless I'm in a forgiving mood or I have troubles with other civs.

If you want to do it militarily... Try launching waves of attacks on their high population world using MASS DRIVERS. Don't throw all your soldiers in on one attack (with a big capacity transport). Try going like 500 at a time with mass drivers, three times in a row, and see if the population dips to where an attack with a bit larger force will possibly succeed (using means other than mass drivers if you are concerned about planet quality). If I'm not mistaken, the planet's improvements and quality will only be decreased in a succesful mass driver attack, but an unsuccesful one will still manage to obliterate a lot of the planet's population.

When invading, it helps quite a bit to have the soldiering line researched all the way through shock troops and to have the tir-quan training center galactic achievement.

the korx are robots and don't sway easily. i have had some of their planets in my space for an entire game without a rebellion.

The Yor are the robots, the Korx are mercenaries.
Anyway, yeah, you could Mass Driver them out, or you could try a really big troopship(8k+) and use Information Warfare for one big battle.

(This is probably already resolved, but IMHO...)
I've found a couple 'information warfare' invasions beat the 'huge # of defenders' strategy. One of the AI's weaknesses seems to be planet defense. I think this is because it's tough for a cpu to look at an overall picture the way a person can.

But when I play on 'tough' or higher I've found it's plenty enough of a challenge. Overall, I'm really impressed by the AI on this game.

That's actually not a bad idea. Presumably those worlds would have abysmal morale, so Information Warfare might be effective for once. Has anyone tried this to see if that's the case?
