I figured it out. The hardcore love toys and stories, casuals love games.

So, according to the OP playing golf by yourself would be playing with a toy, but playing with another person would make it a game?

Yes.

Clubs and balls are toys. If you're playing with a toy alone, you're not playing a game.

Only when someone else starts playing with your toy does it become a game.
