Redcentric did a little digging to compare how virtual worlds and the real one stack up in various ways. Some of the results proved astounding.
With World of Warcraft, Redcentric noted that the population in both the game and the US military have about the same percentage of males (84% to 83%), while EVE Online's male population (96%) is more similar to that of the astronaut crowd (90%). The agency also noted how Second Life has 10 real-world embassies in it and that a previous ban of real-money trading in the game caused a very real financial crisis for a bank that wiped out $750,000.
So how do these three titles compare to real-world cities in regards to population? World of Warcraft at its peak was close to Moscow's population (11.5 million), while Second Life almost hit the levels of San Fransisco (825K) and EVE Online barely surpassed Edinburgh's 495,000.
