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.
Depends on how many expansions you want to get and how long you want to play.
There are currently 13 expansions for the Dominion card game.
You just need to install the original World World of Warcraft. Then you can buy the expansions later, if need be.

one, the perfect one , she is perfect.
Expansions: World Adventures Ambitions Stuff Packs: High-End Loft Stuff
There are currently 2 expansion packs available for the original World of Warcraft. Burning Crusade (First Expansion) and Wrath of the Lich King (Second Expansion). There will be a third expansion sometime in the latter part of 2010 called Cataclysm. So 2 expansions and a third on the way.
Blizzard Entertainment is notorius for not releasing too much information about future patches and expansions. The only expansion that is confirmed is Cataclysm, which is close to being released to closed beta (it's in Friends and Family Beta at the moment and is under a Non-Disclosure Agreement [NDA]). There has been speculation/conjecture/theories as to how many expansions there will be, but nothing is confirmed by Blizzard.
