There are/were some ridiculous holes in the gameplay. In Civ III the negotiation screen after war let you take everything from the enemy in return for peace, unless you upgraded with a patch.
Been a while, but as I remember it, you could offer a high price for peace, then when your enemy rejected it, renegotiate and demand lots of gold, resources tech and he’ll accept it. The patch stopped this nonsense and you had to negotiate. But it was fun for a while
