That's quite besides my point but I'll answer in two ways:

Firstly what defines "working" isn't really your choice. If the goal is to have fun the silliest stuff can be called "working". If the goal is to escape reality for a bit then pretending to be a mermaid might be quite effective.

Secondly, my point was just that there is a game, played by people that are probably enjoying themselves,, which could probably be translated into a Video game. Just like any other sports.
