I think many people already realize that online gaming is going to be a giant catalyst for bitcoin adoption, especially as an MMO in-game currency. It is only a matter of time before you buy your armor and weapons with btc, loot monsters for btc, and can cash out your btc. Imagine the day when you battle another player, loot his armor, sell it, withdraw, and make your car payment.

I project that in a few years btc use in virtual economies will surpass btc use in the "real" economy. If there is anything btc would excel at, it would be for in-game currency. Adoption in virtual worlds could take bitcoins to an entirely different level. Odd that no one is even talking much about this.
