The game is everything that a MMORPG expansion should be, adding story, gameplay, and thousands of new quests for players to complete, along with a plethora of new dungeons and an involving new story. If there is one thing that can be said about Blizzard, it is that the company can consistently take something that seems like a solid game as is, and then completely remake and improve it, seemingly at will. While the fee structure hasn't changed, the game definitely has, and it's worth picking up to experience those changes.
