There are a total of 9 achievements for Italy. They are all pretty straight forward and there aren't any really challenging ones like we saw in Las Vegas. These do take some time and many players are finishing up. The Rome, Sweet Home achievement happens in two phases. First you need to unlock each property in your Village by mastering the corresponding property job on the Bronze Level. Then you need to go to your Village and click on build. Getting to Level I will not require any upgrade parts.
