World of Warcraft Expansions in order are as follows: Burning Crusade, Wrath of the Lich King, and Cataclysm.
As of September 25, 2012 the newest expansion Mists of Pandaria should be added.
That depends what you mean by the question. Yes, you still have to buy the expansion disc to access its features but no, there is no additional payment on top of the usual monthly payment.
Nope, you will need a credit card to buy the WOW expansions.
Nearly every person who plays World of Warcraft will buy the expansions at sometime in their WoW career. They do this because you need the expansions to level higher and explore new content.
Yes it does. I just installed WoW (+ Expansions) via the wotlk downloader.
No, you only buy it if you want to play the expanded core like getting to new maps. I say it's still good without buying expansions.
If you have all of the previous expansions, you can log into your battle.net account, find your WoW game management and digitally upgrade to Cataclysm. Or you can buy the expansion pack at a store.
you might need to clarify this question a bit, but i will answer like i think you want. you can play wow online if you install the client without the expansions, yes, but you will not have access to the updated content in either of the expansions. you will not be able to go to outlands or northrend. you will not be able to create a death knight in other words, just install all the expansions, its lots easier.
unlimited. Just need to be able to have an account and update the account with the expansions.
When you install WoW, it install all expansions and patches up to the current client. This is even true if you do not upgrade your account to BC or Wrath. So it will take about 15 gigabytes.
You just need to install the original World World of Warcraft. Then you can buy the expansions later, if need be.
No. If you mean by patches, then yes you can. But not if you are talking about expansions. you have to buy it. My friend currently plays wow because I got on my account and downloaded the expansion and stuff to his computer under my account for free. That's one of the tricks I do to get people to play wow :)
World of Warcraft will not end for quite a while. They still have several expansions in the planning stages, and they just launched the latest one, Cataclysm.
