Generally I really feel that 3 rows in City Screen as well would be the best solution.
But I need to know if it really works or if it looks so ugly that we can not do it.
Since I simply do not know yet, if
City Screen will work with
3 rows or only with
2 rows, I will go for the "safe solution".
I will add
6 Yields so we will have
96 Yields, which can be divided by
3,
2 and also
even division by 4 would work.
------
The 3 Yields I really want to add for gameplay reasons:
- Everyday Clothes, --> For the Tailor Buildings created yesterday
- Festive Clothes --> For the Tailor Buildings created yesterday
- Pottery --> For the Pottery Building (will give Clay some additional usage)
These 3 Yields I add for "Screen design" reasons to stay "symmetric" *:
- Milk --> I will implement this Yield to be produced in existing Stables by Profession "Milk Maid" / Expert "Milk and Cheese Maid" (needs Cattle / Sheep / Goats, but does not consume them)
- Cheese --> To be produce to be produced in existing Stables by Profession "Cheese Maid" / Expert "Milk and Cheese Maid"
- Kautschuk --> a rare "luxury resource", similar to Silver, simply a plant instead. (No expert of its own. Most likely will also use the "Maple Sirup Collector" as its Expert.)
------
* Do not worry, I have nice gameplay ideas for them as well.
Especially
Milk will do something the mod has never done before:
It will
require another Yield (Cattle / Sheep / Goats)
without consuming it.
Also
Kautschuk as "non metal luxury resource" might also be interesting.
(It will also balance the "South" a bit vs. the North.)
------
Also, now I
really really really try to stop adding trabable Yields ...

Infact I was was really fighting a bit with myself to add the last 3 or not: Milk, Cheese, Kautschuk.
(Now however I kind of like that idea to have all options in Screen design.)
------
But yeah, I know that nothing is perfect.

I am
still "experimenting" to find the best solution.
In modding most is also
simply "personal taste".
Everything could be done in some other way.
------
I know, that this sounds like I am going crazy with Yields.

And partially it might be true, but I also want to optimize the constraints for screen design.
(e.g. Europe Screen, City Screen, Advisors, ...)
If I would have known that both
City Screen and
Europe Screen can work with 3 rows, I would have stayed with 93 Yields (can be divided by 3 only).
But since I do not know, I am not going to take a risk and will have
96 tradable Yields (which can be divided by 2, 3 and 4).
