Answer: You can be any Nation to join the same alliance, you just have to be in the same Kingdom.
Some extra relevant information:
In the popular mobile game Rise of Kingdoms, forming alliances can be a crucial strategy for success. However, it is not necessary for you and your brother to both choose the same civilization, such as Rome, in order to form an alliance.
The game offers a diverse range of civilizations, each with its own unique set of advantages and abilities. While it can be beneficial to have members of the same civilization within an alliance, it is by no means a requirement.
When forming an alliance, the main focus should be on finding players who share similar goals and playstyles, rather than being limited by the choice of civilization. Cooperation, communication, and teamwork are the key factors that contribute to a successful alliance.
In Rise of Kingdoms, alliances work together to defend against attacks, conquer territories, and support one another in times of need. Each player can provide their own strengths and contribute to the alliance’s overall progress and success, regardless of their chosen civilization.
Furthermore, having a diverse range of civilizations within an alliance can actually be advantageous. Different civilizations have unique strengths and weaknesses, which can be strategically utilized to cover each other’s vulnerabilities and enhance overall performance.
Therefore, while it is not necessary for you and your brother to both be Rome or another civilization to form an alliance, it is important to prioritize finding players who are actively engaged, communicative, and align with your goals in the game. Remember, a united and supportive alliance can make a significant difference in your Rise of Kingdoms journey.
