Characters can equip different pieces of equipment that teach them new abilities. This encourages players to strategize and mix and match gear to learn all the abilities available. Another cool mechanic is the Trance system, where characters enter a powered-up state during battles once their Trance gauge is full. It adds an extra layer of strategy to combat. Also, the Active Time Event system allows players to see what other characters are doing simultaneously, providing a deeper insight into the story and character relationships. Overall, Final Fantasy IX’s game mechanics are intricate and enjoyable to explore!
