Hi there! I'm new to the game. I only have the base game and the free dlc's. Question... I understand a little about how the game works but for the life of me, I can't seem to figure out what each tech will allow me to build/construct etc. For example... if I build a constructor with the intent of mining a resource, which tech will "open up" that option to construct a mining ring? Understand, that's just an example. I know I might not be explaining it very well but that's my issue. Simply put... how do I tell which tech will allow me to build/construct/access which item?
