Rebound

Basketball with technological assists and evolving teams (with thanks to Tygon!)

Giant Robot Ball

Football/Basketball inspired sport, but with giant robots. It’s right there in the name, really. (With thanks to Whines!)

Hook

Either space dodgeball with a basket, or full-contact space basketball. Your choice. Quintessential ballball game.

Linerunning

Something between ziplining, roller coasters, and Tron’s light cycles, but without all that protective gear.
