I Updated personal best to 1859-03-29, but the time has extended...
SimCity DS2 has 3 routes, Asia (Japanese edition has Japan), Europe, and America. But America route takes very time consuming, because this route needs shipyard ($30000), when Europe's middle-age. And modern age, immigration events often occur in America.
I have Japanese edition, so I talk it. In middle-age, Europe can construct school early, but Japan can, after half. And large-park, Europe can construct before clear, but Japan cannot. So Japan is more difficult than Europe, but Japan is earlier than Europe for clear. What?
I think traffic-jam is not important, I think large-park is very important. Notably SimCity DS2, pollution is important for land-prize, when highest residence next to a factory across a large-park, residence remained the highest rated. (But, that across an airport, coal-power-plant, residence remained the low rated.)
Password is very interesting, but this game takes a long time to save and load, so I don't know how fast.
