I buy the DlC if i think the content is worth the price. For example fuck the call of duty map packs. I love the game but 15 dollars for 5 new maps hell no. On the other hand i just paid 7 dollars for the dead space 2 DLC, when it really only offers an extra 2 hrs of gameplay, because i love the series so much. I plan on buying the new Mass Effect 2 DlC that is coming out in a week. Fall out DLC is always awesome cause it adds at least 4+ hours of gameplay. It just all depends on the game and if the developer actually wants to expand the experience or just simply get money.
