Inflation is a useful tactic to make RPG style games addictive.
I worked with someone who built a popular facebook RPG game, and part of what made it popular was that as you became an established player the amount earned per day rose exponentially. As the game became more and more popular the virtual economy started to hyperinflate almost out of control, and the established players started hitting the MySQL integer limits. The author never expected that would ever be possible, but the exponential rate of inflation plus the exponential rate of new players joining created a giant pyramid scheme.
Good story, reminds me of a favorite quotation: The greatest shortcoming of the human race is our inability to understand the exponential function. — Albert Bartlett
