Endless Space 2 - Technology Tree and You

Some of my friends said the greatest challenge to them is navigating the technology screen, so I decided to talk about it for a bit in three parts. Part One: How to read the tree Part Two: How to interact with it Part Three: The importance of early game technologies I forgot to mention in part one that depending on your race various technologies will change and are denoted by your race's affinity symbol. I remember to mention it in part three.
