Vault Network's readership includes a very large and still growing number of gamers who play one or more of the massively multiplayer online titles currently available in western markets. Such individuals are almost all familiar with the prevailing revenue model, which involves paying a set monthly fee, most often charged to a credit card, that covers as many hours as they wish. Some are aware that other parts of the world, such as the Far East, use different schemes like the pay by the hour and time card options available in Internet cafes. A few even know that in certain places, you can add such expenses to the bill for your mobile phone. However, it's pretty easy to take little or no notice of these practices by more or less dismissing them as by-products of cultures halfway around the world.
