I just started playing this game, but to me it has nothing to do with the original Settlers games.
There are no roads, which requires planning of routes and priority of goods to carry between buildings. There is no deistribution of goods between storehouses, to optimize what is needed where. The game is missing the whole element of planning how to get everything on the land to run smoothly.
This is nothing but a waiting game (like many others out there), which can be speeded up for the impatient ones for real money.
My suggestion is to actually make an online version of the game Settlers, because this is not it.
