I agree something like that would good for super weapons. The same as nuclear weapons is frowned opon. Although when you think about it, the countries that are super powers and have had them for a long time don't suffer any signifficant penalty. Only really the countries that are developing them.

 When you think about it though, all weapons do some pretty nasty stuff. It would be good if you could claim planets by only taking out military hardware, and not bombing planets populations to smithereens, brainwashing them or taking them hostage. If your a good leader with good social, business and industrial standards, good people should want to be part of your society. It would only need the elimination of the repressors assets to initiate this.

 I like the thought but it may be to late to add something like this. I still think Diplomacy is good expansion though.

That seems closer to 'temptation' than 'odium'..!!  I suppose if the code already exists then you could add a diplomatic penalty for having a large military force as well, it might help to form the stop-the-leader alliances which the AI used to be weak at?  The AI were never slow to attack me when I had no fleet in previous versions, even without the extra incentives!

Not being able to mix unlocked and locked means that we won't be able to have locked humans on separate teams playing with unlocked AI- which is another game type and one that might reward a civics build...  If you can find another means to implement a king of the hill game or maximum number of winners for all-unlocked games it wouldn't be important, as it would clearly be an improvement to have the human players unlocked as well.

It would be good if you could get it to work though... games like 1v1v1 become far more possible with a few unlocked AIs in the mix!
