The reason Feng Luo felt that the game of War was connected to Earth was that, apart from the familiar equipment and weapon names, the names of people and places also served as proof.
When it came to the names of NPCs, there was great variety. Apart from Chinese names like Jing Xiang or Ah Lan, there were also Western names like Andre and Old John. There were even Russian name endings such as -chev and -sky, and the name "Lin" was definitely a unique name.
Under most circumstances, large cities of the Federation contained a mixture of NPCs with different types of names and skin colors. For citizens of the Federation, it was not unusual at all for their names or skin colors to differ. However, there were also cities where people of certain skin colors and names represented the majority.
