I just found an inconsistency/contradiction in the guide.
4. Build Farm
Speed it up
5. Build Sawmill
Speed it up
6. Build Quarry
Speed it up
7. Build Ironmine
Speed it up
...
49. Build 6 Sawmill level 3
Speed it up
50. Build 3 Quarry level 3
Speed it up
Continue building up 10 Sawmill level 3 and 7 Quarry level 3
Build cottages to keep population from going red
51. Build Academy level 2 when resources allow
Turn in quest
I started with 19 production zones. At Line 4, I built a farm. At Line 5 I built a Sawmill. At Line 6 I built a Quarry and at line 7 I built an Ironmine. After Line 50 I built 9 Sawmills and 6 Quarries consuming all avilable production zones. There is no way you can build an additional 10 sawmills and 7 quarries as the guide suggests.
Next...
At this point you should be a Knight with about 2100 Prestige, 40000 Food, 15000 Lumber, 7500 Stone, 10000 Iron
61. Build Marketplace level 2
Maximize all your production squares with Sawmills
Keep only one farm, one quarry and one ironmine
Always sell your lumber and buy the other resources (lumber is the most expensive resource)
It is the Walmart model of maximizing profit per square foot!
62. Start buying and selling resources
63. Create your second city
To see how, hover over the city icon in the bottom-right corner next to the Buy button
In red above it says I should maximize all production squares with sawmills to be used for sales. Does this mean I need to sell off/Destroy all the Quarries I built back at Line 50?
And, I'm not a Knight.
