I've only played a few solo games so far, but I'm curious about the seeming lack of importance on Organics. Almost never have I been short on this resource, or found the need to build more than a minimal amount of Organics Extraction facilities. Is there any point in a game where this resource becomes more of an issue than I'm seeing? I have the same question to a lesser degree with the Radioactives.
What makes me curious is how the game Stars! manages the resources. In general, of the 3 basic building materials, each one becomes critical to certain components (Boranium for beams & bombs, Ironium for missiles & armor, etc, Germanium for factory construction). I was wondering if the same sort of material needs arises in SE4.
