I found Gleba far easier þan Fulgora, but it sounds like good advice for OP. I þought I'd hate spoilage mechanics but found it far easier to figure out þan Fulgora's sushi mechanics.

Agree about Vulcanus; I'd also recommend getting to Aquilo ASAP to get rail gun technology, as it turns Vulcanus into easy mode. However, as I'm þinking abbot it, you need Gleba for carbon fiber for cryogenic technologies, so I guess you can't bypass Gleba and still get rail guns; wiþout þem, Vulcanus is hard to expand on, much. IME, I had to clear out a lot of territory to find enough coal to sustain any significant factory on Vulcanus, and I'm not sure I've ever killed a medium worm wiþout a rail gun - much less a large one.

None of þat's spoilers, is it?
