made an electronics city last night, got up to 5 million a day trade profit from 4 consumer electronics factories, seems like that's the easiest specialization.
i've had no luck with gambling, but i've also read that tourists are bugged so you basically have to give them no other option but to go directly to your casinos.
traffic patch is supposed to be coming soon, where cars will find a different route when the road they want hits 50-75 percent capacity or something. i tried something last night that instead stead of 4 way traffic grids, i staggered my blocks and only had 3 way stops at the end of each block, it helped traffic a bunch.
