Just to give you some food for thought:
Mining the roaded plains hill tile fairly soon probably makes sense. Cities A&B can both use it when building workers/settlers (while the other one uses shared fish tile to grow). And as discussed earlier, City B needs a new improved tile when it grows to size 3.
And I'm starting to think that the 90-hammer library is just a bit too much at this point (e.g. barracks+worker could be a significantly better use for that investment), but let's see!
