I appreciate how the focus is on growing your character by earning experience points. At the same time, you have the option to play solo without interacting with others. I love teaming up with other players to complete quests and battling it out in PvP combat. It has a gripping storyline set in the world of Azeroth, and you can explore it in first or third person views. This is the most successful online multiplayer game ever, and for a good reason too.
