A NEW project!
The test of the other city was going nicely with a good result in-game, the more visible problem was of the intersection sidewalks corners, just because they weren't correctly made. So, he has already done a successful test like you suggest, now he can just go ahead with a new one with correctly made intersections, and then go ahead in that way with the making of a such big city.Try a small, rectangular map, with roads following a grid-like pattern. Dont make more than 5 roads or intersections. Once you get the kinks sorted out on this, then move on to bigger things.
