Abstract: Methods and systems for efficient establishment and operation of a league (e.g., a competition league, an athletic league, a sports league, etc.) are provided. For instance, a bonus league may be established based on a parent league. According to one or more aspects described herein, the bonus league and the parent league may be established and operated to mutually benefit one another via improved resource utilization (e.g., which may include improved management of player resources, shared team branding and merchandizing, shared marketing, shared stadiums, and shared likeness, among several other examples). The described techniques may additionally provide for effective cross-promotion between the bonus league and the parent league, as well as refined systems for testing and evaluating one or more aspects of the parent league (e.g., as the affiliated bonus league may test and evaluate new rules, rule changes, uniforms, game tactics, marketing strategies, etc.).
