Expansion Packs

[Sylar]

I know some online games have "expansion packs" that you can buy to add more content that you can play. Anyways, do you buy these expansion packs? If so, why? If not, why not?

I personally don't see myself buying expansion packs for SWTOR, although I have bought map packs on some of the CoD games

I chose not to purchase the Euro 2012 update for FIFA 12. There are already enough game modes in my opinion and I don't really remember hearing any good reviews about it.
