Thanks Xeno,
Could you perhaps elaborate on the "constantly switch cities" comment?
I understand the benefits of having inter-connected cities, so doing it solo means you'll have to build up multiple ones. But once they're in the 'final stages', would you still have to keep switching cities to gain a benefit?
Or in other words, does the act of being online in a city but not doing anything extra to progress, still give a benefit to trade (or other things) with a connected city?
