Your comment is definitely true. While the argument that sports are cheaper than video games does have some merit I contend that the barrier to entry for video games is much much lower than sports. With video games their learning curves are typically very gentle, you can play video games by yourself if others aren't available to join you, you can play from home, etc.

That's not to say that anything is wrong with sports, because I definitely feel sports are awesome, but rather that I genuinely feel it's easier to jump into gaming than to organize a team sport like a game of basketball at the local park.
