Buildings
From Starfleet Commander
Buildings are the structures you create on your planet to help you develop your empire. Each building must first be built and then can be leveled up to increase its effectiveness.
They include a few basic types of building.
Mines
Mines are the primary method of resource production in Starfleet Commander. You are allowed one of each type of mine on a planet.
Factories
These are where you build the droids and ships that power your empire.
Research Lab
This is where you discover new technologies and upgrade your empire.
