My only objection is that in a computer game you can do things instantaneously with the click of a mouse.
While yes it is just clicking it still takes a amount of time to collect the proper amount of items then click on the building the proper amount of times to complete it. Im sure for a child it would be entertaining and yet "painstaking" just enough to keep interest instead of completely deterring them with hours of game play and one little lean too to show for it. Trying to find a balance between realism and entertainment value for a child with a video game based on survival im sure is a near impossible thing.
