Oh, that reminds me that I kind of wanted to include additional GP actions.
Yes, GS is a bit useless now so he could be boosted a bit up.
Anyway would it be the best way to approach this matter by posting saves where AI refuses vassallization despite it would be beneficial.
Some ideas what would make AI more willing to become a vassal:
- tech difference, more techs you have the better
- higher score the better, ai should use this like tech difference to become under your "umbrella" and try to milk some benefits like techs and resources
- distance from border and capital, currently it makes a little sense that civs apart globe becomes each others vassal. Inca specially often have complitely bizzare masters
- number of cities should not matter but less cities civ has more willing it should become a vassal
- direct opinion, there also should be an option "become vassal or war!"
- and most important is military strenght, are you in war and military strenght inside civs border. Like if you have more military strenght inside your targets border AI should understand it should surrender and not to be destroyed
