The logistics system really needs to be optimized. The first thing to be affected is the wagon. Players have no idea of its behavior logic, and it doesn’t seem to transport sand. If possible, it might be a good idea to add a mode for the wagon to specify a pickup/unloading building. Alternatively, add a small freight station covering an area of 2x2, where 1-3 workers can deliver the specified goods to the specified building as much as possible. In addition, the game can have a built-in indicator showing where the production building gets its raw materials, which can effectively help players optimize logistics.
As a decoration that does not increase the “attractiveness”, can the box have some practical uses, such as increasing the upper limit of its raw material storage when placed next to the production building?
Level 3 roads are indeed very attractive, and the materials they can require are more demanding (for example, stone + sand + coal mines), as a means to further improve the efficiency of the town in the later stages. It can only improve people slightly, but can make the wagon transport various materials faster (if possible, can the wagon be upgraded in the later stage to transport materials other than ore between market-market/market-warehouse/warehouse-warehouse)
Can the trade station enable the order reminder function, select some goods, and give additional reminders in the upper left corner every time a merchant comes to sell these goods.
I guess I have encountered something strange… My glass workshop is next to the stockyard, but the wagons will not transport sand into it (there are 4 wagon shops with a population of 500, which should be enough). Instead, the glass workers will go directly to the sand pit to get sand.
You need more sand stockpiled for the logistics system to work.
If the glass workers have no sand, they’ll send one of their numbers to go and get some rather than standing around doing nothing. The wagon, on the other hand, will prioritise moving hundreds of clay rather than a few paltry units of sand. But, if you have a few hundred sand in the stockyard then everything should work fine. The glassworkers will work on making glass and, before they run out of sand and need to go get some themselves, a wagon will deliver it a large amount from the stockyard in one go.
The logistics system isn’t perfect, and there are edge cases where really odd things happen, but most of the time it works well enough if you have buffers of each resource lying around. It’s not “clever” enough to handle a just-in-time production chain that spans the whole village. IMO, that’s fine, the game isn’t Factorio. If anything, it’s already unrealistically clever: your villagers have perfect real-time information about how much of which resource is where and who has already reserved it.
Personally, I’d much rather logistics become less important, than add tons of micromanagement by having to assigne individual wagons to individual transport routes.
