In the comments to the video I already proposed that bloodsports would be a mine for this.
Inside Cyberpunk 2077 you could play these bloodsports two ways:
- If your character is physically apt, they could enter the real league.
- Everyone else, including them, could play a videogame version of it in whichever implanted portable or implanted device they have.
The real league would be deadly. Real athletes would be maimed and have their limbs constantly replaced. Maybe even have prosthetic bodies specifically designed for the sport like Gally in Gunnm/Battle Angel Alita. They would even die irreversibly.
The virtual version, it would be implied, is a common pastime for people of all ages. It would include two main modes: playing the actual sport, like one plays FIFA or Madden; and playing a team manager, a kind of fantasy football. In this fantasy football you would be assembling your team and managing their day to day: contracts and wages, injuries and hospitalization, doping and enhancements... The players and special gear and cyber would be the collectible aspect, and it would be especially funny if it would expand on the world building by tieing into it. "Oh, they didn't take this athlete's likeness from the store even though he died/ was caught in a drug or sex scandal/ you name it...", or we're playing a pirated copy or using our Netrunner character to rig it or whatever.
I think this bloodsport mode could be greatly expanded as its own thing and cater to an entirely different audience than the core Cyberpunk 2077 and Gwent, while allowing for a great and meaty distraction in CP2077 proper.
