My first impressions of this is version of settlers is good, but every version of settlers has the concept of resource chains.
So the raw resources building are place near / on the raw resource ( like ore, wood cutter ) but it is only every delivered to the nearest store / mayor house. Every other type of building only retrieves from the store house.
This is contrary to every other version of settlers to date, where the resources are delivered to the front of the building then transported down the line / road to the next carrier. Sometimes this ended up at a store house, but you could put a sawmill next to the wood cutter and get a much better efficiency. Same for flour mills ( next to wheat farm ), butchers ( next to pig farm ), and so on.
In this version when the resource delivered to the nearest store house then this is instantly available across the entire map. Buildings requiring a resource from further up the chain ( ie fir wood ) benefits from being nearer the store house, not the source of the resource, since this is the only place the raw material an come from. So you end up with concentric rings of buildings around the store house.
I realise this is a web version of the game and that it is always running, but you have fundamentally changes the economics and mechanics of The Settlers game. Surely there can be come sort of compromise between working out where the resources are in a supply chain and a simplistic time/distance calculation to increase a raw resource count.
