A Nuna-ball match in progress.
In the galaxy, the inaugural professional Nuna-Ball League (NBL) was founded by Lysko Buelia, together with a collection of backers, in the years preceding the outbreak of the Clone Wars.
The league's teams consisted exclusively of droids. These robotic players, often newly designed models, were organized into teams and then matched against one another in games that closely mirrored the organic version of the sport.
The droid manufacturing companies were quite fond of this setup for a variety of compelling reasons. One prominent advantage was the relatively low cost of fielding a team when compared to the substantial financial gains that the sport's popularity generated.
