How do I know it's working?
When you click on a city that box appears in the bottom right portion of the screen. Hover your mouse over the production symbol (kind of like if you were going to order your city to focus on production) and the popup tooltip will break down your production numbers. Factor and power plant will show up in here.
I have a question. People are saying Toronto is a bit weak as a city-state now. But I don't understand how. It seems to me they are even more important than before. Of course you shouldn't rely on them unless they are close by. I found that out one game when they were conquered and I was too far away to do anything about it. I did have Toronto in my last game, but to be on the safe side I planned industrial zones around the 6 tile rule. Thank god they gave us map pins to plan out industrial zones and entertainment districts.
So far I'm okay with the new rule. It's kind of a relief not to have to build these in every city. Of course the reduced production means I still get behind in building things even without the necessity of having to build industrial zones. The only way I can get "caught up" with things I need to build is to buy things. Most often I end up buying builders as I seem to never have time to build them.
