I usually play on king, my last game I started on emperor as America, so far this is how it is coming along... All was quiet, I was minding my own business, building up towards a tech victory and stashing gold away. Had several lux res, flowing throughout my country. My people were happy, my vertical building was going as planned, all was well. China was small, to my west and friendly and so was my other neighbors to the south. I thought, looks like I could pickup an easy tech win here. Then, I had the bright idea to start settling cities near China. I was hungry for more land, greedy and wanted more. First I put a new city very close to their eastern border. Now, many of times if they have a problem with this they will let you know quick. I never heard anything from China, plus they were small and even though I never had much of a military, I was not afraid of them. Also, they have been friendly the whole time. So, I figured I would sign an open borders with them so I can pass on through and settle in another location near them I was eyeing out. The open borders was signed and I had two settlers on the way to get two more new cities setup for my country. Not long after the first one was founded, I noticed an enormous buildup of Chinese forces. They were starting to crowd near that new city. I started to become concerned as I had production orders all setup in my other cities, and very minimal military. Small as China was, their military was definitely to be concerned about. Only 1 turn after, China came up and said, "I have the advantage now, I will destroy you", something like that and they declared war on me. Thats exactly what they had, and they had moved it all into position, perfect execution and I was in trouble. Not one barracks in any city, I started the construction of at least one. Then started getting chariots in production. I lost one city, then another, then they moved in to take my capital which they did. I struck back pretty hard, retook my capital, but now I am facing another wave of attacks. There you have it, I posted some screenshots below. My northern city on the coast, was getting bombarded by 3 ships and its down to nearly nothing so they will probably take that soon too. I may can hold out, but I doubt I will come back and win this one, I will try. I was surprised, I really did not think they would attack me, I never seen them do that without saying not to settle cities near them and give me at least a warning. I did figure they would not like that but they never said nothing. This has been a fun map so far I will say that much. This game still has a long way to go, its not but a little past 1300AD right now.
