As you progress, constructing buildings and wonders becomes crucial to improving your civilization's defenses, scientific research, trade, and food output. There are 28 Wonders of the World in total, each offering unique advantages that can be used strategically.

Combat is a significant aspect of the game, with battles occurring in cities or open terrain. Defenses are advantageous when fighting on uneven ground, such as forests and mountains. However, losses are always permanent, with defeated units disappearing from the game and leaving behind damaged units that need repair.

Keeping good diplomatic relations with other civilizations is vital, as they can become allies or enemies depending on your actions. Trading knowledge or pooling military resources may be beneficial at times, but betraying these agreements can damage your reputation.
