As we all know, different people have different taste, so for everyone, they must have the different treasures in their heart. In my opinion, as a game player, I guess World of Warcraft CD Key is a treasure for somebody.   
Maybe their will not so much person like to play the online game and some of them do not know it. I think there still be many have the same interests with me, they like to play the game WoW, and they all have a lot of WoW CD Key in order to make them happy in the game. Just as the person who want to have some money to entertain them.  
I have ever heard a story said that: a woman has two sons, one is a farmer in the country, and the other is a worker in the city. One day, she wants to divide her family property to the two sons. After she divides all the things except a cattle and an ancient sand pot, she does not know what to do and ask her brother to help her. Her brother then says that the cattle give to the farmer and the ancient sand pot give to the worker. Because they are all have some use to each other. I think the brother is right in the events. The farmer likes the cattle just as the worker likes the pot to have some drinking. On the other hand, it is just as I like the World of Warcraft Game Cards to have my game.   
Now, let us come to the game I played for several years which bring me so many smiles and make me crazy. It is not pile it on but to say my true feeling on the game. In my leisure time, I would stay in front of my computer and use my game gold to play this game. Because of I have won a lot of this game gold, I do not need to buy WoW Game Cards the next time. I love this game
