Well, Amityville (my first town) finally broke 300 people tonight in our year '53. I actually ended the night at 377 people. Grew too fast at the end there as my food supply dipped below 10K for a year or two. I had to quickly build some new farms and fishing huts in order to make it through, but I reacted fast enough and now it's stabilized again.
My map has lots of mountains, so my town is rather spread around currently. Tomorrow I'm going to expand into the NE which has a real nice large section of flat land. Gonna grow a huge town complex and see if I can't break 600 by tomorrow night.
I also now have traded for all of the crops, seeds, and livestock. Got an achievement for it too. This game is addicting, so much like Civ in that regard.
