Timing is the key.
Wait to settle until you have extra gold - Then settle + buy 4 tiles on the SAME TURN, and you will have a magical message to stop doing both. If you have no more need for that zone of the board, agree to both and you will not regret it.
I often find myself in situations where the AI tells me not to do something i already intend not to do anyway or asks me to do something i plan on - it's like when your opponent puts you into check, so your counter move checkmates them.
Its like a group game of magic the gathering. Player 2 does a kill everything effect, player 3 looks at me for a counterspell. He knows i have one, but i think it behooves me to allow this soft reset effect. Player 3 promises that if i counterspell Wrath of God, he will not Lightning Bolt my Chronatog. I have to assess the sincerity. He might lie - but player 3 and I both know that if my chronotog is still alive at the begining of my next turn, i win the game. So, to counter or not to? I should not counter because either way i pose to lose my 'Tog and i would rather not lose my counterspell to prevent something that will already happen anyway. I tell player 3 "Use all your instant burn spells right now, and if you have less than 2 cards still in your hand, i will counter it."
Can player 3 burn away all his cards and still win? Can he trust me to counter once his hand is empty? Does he have an Ace? And lastly, how does this situation effect Player 2, patiently waiting to reset the world?
This is whats missing from Civ.
