Hello, I’m looking into the add-ons and I’m just unclear on a few things: 1. How compatible are the materials from the old books with the revised edition? 2. Are books like the Ships from the Expanse still relevant, or is the new Players companion book largely reintroducing the same material with some extras, and more polish? 3. Do the adventures (such as Abzu’s Bounty) add anything in terms of equipment or rules?
