"Random set of goals" could work I suppose. But "Random set of achievable goals" might be better. I played one round, noticed that food drops pretty quickly, and the cards didn't include a lot of "+food per turn", so bought the boar farm to balance it out for future rounds...
Only every game I've started since then wants me to get 5 population. And I only have +2 population from a single camp, and +1 from a single tent. So I can't win any games, which means I can't research any new cards to gain more population. Given that every game wants that, it doesn't appear that the population target is random, which means I *needed* to buy a different card.
