The only ones I've found so far are Good Neighbor and Diamond City? Are these it? The only 2 cities in the entire Commonwealth?

One of my biggest gripes with Fallout 3 was that really the only 2 big cities were Megaton and Rivet City. I really hope there's more.

I only found those 2 so far as well though there cud be more since theres a lot of the map i havent covered jet. Btw you do know you can create your own large setlement with shops and everything right so even if only those are premade you can make many more if you desire so.(damn i just hope they add us more building options cuz i wud rly like to make some concrete buildings and proper houses instead of being limited to wood and metal shacks with holes in the wall)
