Well, I am beginning the final push. I took out two civs while friends with Denmark, but no friends left, so no real trading partners - I am on my own. I just got a beachhead and took two cities from Siam (admit, you all want to do it to the guy). He offered me some money (no cities yet - he is still too strong) for ten turns of peace - I figured, what the heck, I can re-group my army and prepare for the next attack in 10. When you get an offer like that, does it make more sense to do that so you can position, or does that give him more of an advantage to set up his defense, and perma-war is smarter?
