I just recently started playing C5 BNW and I'm having a really hard time winning a cultural victory with Brasil. I'm playing with all standard settings. My last game I was on a continent with Egypt and Nebuchadnezzar. After turn 100 or so they just would not stop declaring war on me. I traded all my extra resources to them and even gave them free gifts. They cut me off from all trades and it got to the point that I couldn't produce anything at all and was basically having to defend until they both eventually got bombers and sacked my cities. What are some tips that I could use that would help me next game? I really don't know much about tile management vs growing city. I usually try to just focus production and build as many buildings as I can, but even then Egypt had like 15 wonders while the rest of us only had 2-4.
