Topic: Tech tree
I assume we'll need one of these sooner or later. Behold, my first draft of a Starmada tech tree:

Color codes indicate defense (green), offense (red), movement (blue), or fighters (yellow).
Everyone starts with the techs in bold (and presumably some fixed number of additional techs).
Techs connected to the left of a tech (by adjacency or a line) are prerequisites.
