I just have to make a couple of comments. I have just checked out the three Adventure hoods in Build Mode, and here are some things I just SWOONED över:
1. The roads. They look fabulous. Different, versatile..
2. The bridges
3. Lots of new deco items good for period building.
4. Fountains!!
Overall the three hoods are beautitifully done, and I just can't wait for the World Creator.
Oh, and in China, check out the walls around the city. Those walls, we need similar for medieval cities.
