The Hegemony wishes to organise not only terrestrial games within the inner colonies, but has also wished to establish major sporting events for the other colonies in low gravity environments on top of this they even play a Olympics like event for the "Spacers". Examples of colonies that wpuld host these sports would be: Deimos, Eros, space colonies not built like Oneil cylinders, but more adhoc in nature, oneil cylinders with zero gravity sections, and any other colony significantly lower then 1g (earth standard). Martians gravity is the minimum on this scale (anything below martian gravity would count as "low gravity" in legal terms)
But they have run into an issue: what should the sports be like and which ones could be easily adapted to zero or low gravity for both entertainment and revenue for the larger space stations? What kind of sports could make the transition to space/be adapted without losing to much of the "feel" of the game? Personally I think basketball is a good contender.
Note: If you have a idea for a new sport that is vsygly similar to one on earth have at it
Logistics wise. For whatever reason sports are big business across the system so even if building a mass ice stadium is inefficient (a few would still exist) streaming would be a major industry.
By sports I mean basically anything from racing to lacrosse and everything in between.
