How Do You Get a Peace Treaty?

I believe there is a setting in the data files 'Mega Evil Empire = ___'. This will have all the computer players declare war on you if you have a score that is a certain percentage higher than everyone elses. In Civilazition II the same thing happened once your score got really high all the computer would team up to try and stop you from winning. So if you want to still be able to use diplomacy when you are ahead of everyone you could raise this number, I think it's in the general settings.txt file.
