We should repeat our last turn, it went well. Minus sending the crystal through, Lets keep one back just in case.
I contest the decision for a larger silo. At least this soon. I feel that can wait until the later months of the year, (its only a few months of woodcutting labor to acquire after all).For now we only have a silo ~1/5th of the way filled, and it will be much less filled come the new year. Is it a good move to upgrade? Yes. But I say not until midsummer at the earliest.
Now hear me out. A Silo is good, but its about what will best strengthen our position. A larger silo may not be the greatest improvement we can build for 150 wood. We're in no danger of currently filling it and wasting food. Not only that, filled it provides us with more than 5 months stored food easily with our current population. Not even remotely threatening. Even assuming we get 20-40 more migrants there is no way, currently, a full Silo (and wasted food) will threaten us during winter.
Therefore I am forced to conclude that for 150 wood we have at least 3 stronger moves that we can make.
The first, is a Wall lvl 2. 120 units of wood and two months of our builders time. Will give us: Added security, peace of mind. Strength of proposal? We are not currently directly threatened but I personally would feel safer having this building.
The second, is any single resource building upgrade. These are currently trivial costs. A few months of gathering and they would be ours (with only 2 months of build time for each). Even a level 3 Windmill is within our grasp. And -that- would give us potentially a filled silo.
The third of course, Is an upgraded HQ. This will allow us more buildings and upgrades that may be helpful.
And thinking on it further while I wrote this, A blacksmith is also a fine potential building, but I believe it should be slotted after a wall.
Additionally, I know I'm rambling a bit, but I support sending 50 ore through for people.
