The merger of the stars and the vassal States is a pit.

1, right. In the strategy game "Journey", in order to resist the invasion of alien players, the players of the Star Empire decided to merge the vassal states, rally their forces and form a United front. And those countries were poorly equipped, with extremely poor combat effectiveness, and suffered a fiasco in World War I. Players said: This is a pit cargo, expressing dissatisfaction.

2. make a reservation. After the merger, the leaders will stay and will not disappear. Leaders will gain experience, upgrade and develop skills. Leaders are recruited by influence, so the influence in the early stage is very important. You can gain influence by announcing your old enemy.

If the population is too large, it can be cleaned up. The national policy allows forced migration, and then the population who wants to move is forced to move. Opening this policy will make the happiness of egalitarianism not high, and it will never exceed 60.
