Gamers have money. Why do gamers have money? Because they do not spend it on things that do not involve gaming. Gamers are intellectuals and favor to spend their money on increasing intellect or allow their imaginations to flow outward in expression.
Gamers are not concerned with the last fashion, the newest haircut, nor any new furniture that is not worthy of the gaming den of comfortable. There is no rush to take the money on these concerns.
This may lead to gamers becoming collectors of said products they enjoy. They may invest in expansion sets, upgrades, and the latest versions of games. They will also invest in ways to keep those collects in good condition.
Businesses that court gamers for their intelligence, skill of games, and love of products will see a long healthy relationship with gamers.
