I'm happy to see that you like the new residential district more! ^^
PMD: Silver Resistance isn't one of the official games, by the way. It's actually a fanfiction. It's pretty good, and one of my many unachievable goals for my own writing.
And yeah, Utopia is mostly rural, since lots of Pokemon aren't particularly smart, or don't have hands, but all the Clans are very, very different. Some of them might be adept at magic, and use spells to do what they can't with technology. Some, like the Rahzyne Clan, simply raid other Clans for what they don't have. Some are capable of sustaining themselves on their own, but don't particularly like the other Clans. While others, like the Muli Clan, have lots of allies, and share technical advances until it gets extremely advanced for a civilization of Pokemon.

And yeah, I really need to make a map of the Utopia region... But that would mean I would have to make a decision about exactly how many Clans there are, and I'm really not too sure about that right now...
