Every game is in your head. Every one else and every thing else is abstracted and coloured by your perception of what is real and what is not.
So get used to playing single-player games. Meditation, yoga, deep self awareness, self acceptance, being comfortable with yourself in a room with your own thoughts – these are not just life skills, these are superpowers. If you can master the single-player games, the abstracted multi-player games become much easier.
