For the price of the Iraq War, we could've let all 2004 Bush voters and everyone 15 or over in the 'Axis of Evil' play World of Warcraft together for a century.
62,040,610 Americans voted for George W. Bush in 2004. About 16.2 million residents of Iraq, 51.2 million residents of Iran, and 17.9 million residents of North Korea are at least 15 years old. This adds up to 147.3 million players. At $40 every two years for a startup or expansion disk and $15 per month, they could play for a century for $2.95 trillion, which is less than Joseph Stiglitz and Linda Bilmes' estimate of $3 trillion for the cost of the Iraq War.
