If we are going to discount games as "just games" let's take a look at what we are minimising.
Let's start with the Olympic Games, every four years a bunch of countries have about 30 sports in 300-400 events, with a worldwide audience.
There's the Winter Olympics as well.
Then there is golf, some 30 million rich folk in America alone.
Which roughly matches the 30 million that play League of Legends.
Then there is The World Game of Soccer. Estimates vary, with some 250 million estimated to be playing and about 3 billion people involved in the sport, in some way, playing or watching.
All told the World Sports Encyclopedia estimates there are about 8000 different sports.
That's just the sporting games.
We also have the big money games. Gambling games. Gambling makes the most money of any entertainment industry. Casinos, poker machines, televised poker games for million dollar prizes.
Then there are the more traditional games. Board games, like chess, checkers, Monopoly. Dice games like Yahtzee. Card games, and so on.
The internet has opened up gaming to worldwide audiences. With some of the big players being League of Legends, World of Warcraft, Angry Birds, Bejewelled, Farmville and its spinoffs, Candy Crush Saga, and again the list goes on.
When we talk about games we talk about the entire population of the world, we talk about a multi-trillion dollar industry. So many people and so much money it's not imaginable.
Just a game.
