WOW’s gonna have tradable game time in the new year

Christmas! New Year! WOW has had an eventful year. And if you have read the post “World of Warcraft in the New Year” in the official forum, you must have learned that Blizzard is trying a new way to play WOW—buying tradable game-time tokens for the purpose of exchanging them in-game with other players for gold. This is the original passage:

New Ways to Play
We’re exploring the possibility of giving players a way to buy tradable game-time tokens for the purpose of exchanging them in-game with other players for gold. Our current thought on this is that it would give players a way to use their surplus gold to cover some of their subscription cost, while giving players who might have less play time an option for acquiring gold from other players through a legit and secure system. A few other online games offer asimilar option, and players have suggested that they’d be interested in seeing something along those lines in WoW. We agree it could be a good fit for the game, and we look forward to any feedback you have as we continue to look into this feature.

As it has stated, this is not Blizzard’s innovation. Several online games, say Guild War, ArcheAge, have similar play-to-pay gameplay. It gives players who play the game a lot to have a chance to earn their subscription through gold. It also gives players that don't play the game often but are well off financially to have a chance to earn gold through selling paid tokens.
