Resources Department got new members from the Staff Recruitment thing, you'll notice an amazing boost in productivity! New items, resources, machines, the WHOLE sh'bang!
You'll have to find out in game how to do this and mess with that. That's the purpose of the game. Society Development. If, say for instance, a new tool were invented real life - what would happen? They'd advertise it (Tell others), produce it (Make it), and use it (Do what it's for with it) - this is the same in game. Think of new items as new inventions, and there's a little nugget in your brain that connects to the invisable Gods above you. When they think of an invention in their magical workshop in the clouds, you then learn how to build it. But the Gods and greedy and don't tell you how to use it. That's for you to find out.
Please believe this story. No, it's not a coverup

I love being a God.

[Please Note: We do not hold Gods captive in our magical cloud workshop and force them to work. These rumors are untrue.]
