I love big maps, heh. It gives me enough time to build my main city, and a few smaller settlements (barracks and watchtowers usually). I just enjoy stretching battles so long as I can. By just building a big army in your main city, while you play around with incoming enemies in the settlements.
And, not that long ago, I waited a bit too long, against the wrong enemy. :} Looks like she was just sending scouts to see my progress, while she way growing a huge army of herself. What a fine battle that was, she destroyed my first settlement. She had to retreat from the second. While I was rebuilding the third, she killed all my workers... :} that battle lasted over 2 hours, heh.
