I've been playing this region for a few months now.  (don't have tons of time each day to play though.)   I'm not trying to get skyscrapers in all my cities, trying to make cities that are nice and liveable and pretty, but I'd like skyscrapers in some of them...).  It seems like people make cities that are "specialized" : residential city next to commercial city, the residentials go to the commercial to work... that kind of thing hasn't worked for me.  If a sim needs to leave the city to work he has a "long commute" and abandons because his commute is too long.So I've been building this region up city by city in hopes of  increasing general demand, but each city needs to have enough jobs to fulfill the needs of its citizens.  So every city has industrial, residential, commercial.  And I'm having a hard time keeping commercial demand up across the region despite lots of Sims living in it.  (About 700,000 sims in region at this point.) Placing landmarks, airports, tourst traps etc.  My cities get to a certain level (60-70 k sims) and just plateau out.  My biggest (large tile) city Cassadaga has about 75000 and is starting to show "no job" zots and since the commerical demand isn't there, how can I grow it??  Any advice?
