You call it a game, some of us call it mathematics. I agree it's fun
though, that's why we spend a lifetime doing it...

Except that set theory is the most formal of all mathematical
disciplines. Without precise definition it is nothing (and very easily
made inconsistent). You can take whatever useful construct you like and
choose to call it a set if it pleases you, but usually it's helpful to
use standard terms with standard meanings.
