Currently there are eight playing classes (see below), but this is subject to change when the new expansion "Wrath of the Lich King" is released later in 2008.
You basically roam around inside the dynamic online world called "Azeroth" killing beasts, monsters, giants, dragons and even other players of the opposing faction if you so wish, while completing tasks (quests) to earn virtual money and items to improve your character and take it to the next level.
There are currently a total of 70 levels in World of Warcraft, you start at level one and as you progress in the game you gain levels, making your character more powerful with better character statistics (strength, stamina, intelligence, spirit and agility) and abilities/spells (depending on what class you choose/roll).
World of Warcraft is the most played game of the MMORPGs, connecting a huge amount of realms over several continents and countries. With over ten million subscribers --and growing-- you're sure not to adventure alone, but can of course if you prefer not to adventure with other people.
World of Warcraft has always been the gateway MMO for a lot of people new to the genre, it is a fairly simple game with a fast learning curve, the game only becomes as advanced as you want it to get.
The user interface is very simple and easy to understand, but for people that want a different look, or more advanced control there are custom user interfaces and interface enhancements to download from various World of Warcraft Interface sites. But for the inexperienced, the basic UI will take the new player to the highest level without any real need to change your UI.
