This is a world similar to Earth but with a highly developed sports industry. The most popular sport in the world is "Ultra Basketball", a competitive event that combines traditional basketball with extreme physical fitness. The rules of the game are similar to those of the NBA, but it places more emphasis on physical fitness and tactical coordination. It has a longer season, more intense confrontations, and a global super league system.
World background: The sports industry of Star Era accounts for 15% of global GDP, and professional athletes enjoy a transcendent status. Each country has established a "National Sports Training Administration" to select talents from young people for training. There are five top leagues in the world: North American League, European Champions League, Asian Super League, South American Libertadores League, and African Glory League. The "World Summit" held every four years is a grand event that attracts worldwide attention, comparable to the real World Cup.
Social culture: Sports stars are social idols with huge fan bases. Sports betting is legal but subject to strict supervision. Sports shady stories, club struggles, and commercial interests are intertwined, forming a complex sports ecosystem. Children from ordinary families have dreams of changing their destiny through sports. The competition is fierce and cruel.
Technological level: equivalent to that of the early 21st century. There is no high-tech assistance (no genetic modification, mechanical prosthetics, etc.), But it has advanced training equipment, data analysis systems and medical rehabilitation technology. Sports competition purely relies on human potential and will.
