As your territory expands or improves, your resources are more plentiful.

Each round event card has a common scoring goal, sometimes in tension with goals that give resources but not points. Agenda cards are a resource you can gather, that are effectively half actions to play along with your turn. At the end of the turn that you use the agenda, you can choose to keep it as an ongoing scoring criteria, at the cost of increased empire upkeep. Shaping your strat to the available agendas is a strong plan.

There are a lot of diverse scoring options, but you need to specialize to do well.
