YMMV: Tuf Voyaging

  • Anvilicious: The S'uthlam stories indicate that overpopulation is a major threat. And "A Beast For Norn" tells us that blood sports are bad.
  • Deus ex Machina: In-Universe. A certain civilization faces extintion by overpopulation, famine, disease or what seems to be a global attack by some unknown lifeform, and then, this giant spaceship pops out from hyperspace and solves the problem... for a price.
