Last year I did a post called online game earner. It was about how you could earn money playing games online. Technically these games are e-commerce where websites sell virtual currency. These games attract a massive participation. Hence the name Massively multi player online (MMO). Many of these type of games involve some degree of role-playing turn the MMO into a MMORPG.
Where the online money is earns is from converting virtual money into real money, this is know as RMT or Real Money Trade. As mentioned in my previous post World of Warcraft (WOW) has gold as its currency and the RMT happens within the game.
If you are into games online and want to make some money out of this then World of Warcraft is probably just up your street. You can Buy Cheap WoW Gold and sell Wow Gold, Incidentally, there has already been an online gamer who achieved the millionaire status., in real money! Many online gamers of course play for nothing, why not earn at the same time?
