Nice game, MG, and good map. I conquered (almost) in approx 500AD, leaving only Tronheim as a trading pet. That was about 2-3 weeks ago. The rest was buildng up the population under Republic, which is useful for GOTM score, but relatively boring. I continued off-and-on up to the deadline yesterday. By then, I was in the 600-800AD range, with about 100 cities, I guess.
I froze science before Feudalism and never got Nav/etc, just to maintain trade. So, I had to leave a LOT of huts unpopped. That was frustrating, but probably correct... not sure.
I didn't have much trouble finding places for cities. I got mapmaking about the time the top of my "O" filled up, and then could move settlers overseas. I did have some problems with the natives, and lost several outposts, but it wasn't too hard to start over. A fun game.
