During the game you will meet new people, make friends with them and collect many different types of armour, also you will be able to reach the level of 70 if you work really hard. However there is a problem with the company who made it because some people are creating World of Warcraft Private servers, which allow free game-play and are taking many players from the real World of Warcraft servers.
Some benefits of a Private Server are that you can create objects if you are what's known as a Game Master (GM) or get instant level 70 whereas on the normal servers you would have to work hard to reach that level so many people decide to play on the private servers and not the real blizzard ones.
