Usually the time/price ratio is much smaller than the released product's, plus there's also a noticeable drop in quality compared to the main game making the DLC feel too much like a cash-in. Therefore, I do not buy DLC, and I also believe that the resources spent on DLC could be put to better use, such as fixing problems with the original game (Fallout 3 & NV, anyone?) or developing an expansion pack using the existing engine that delivers a similar, more polished experience at a fraction of the development costs. Bottom line is, DLC is a waste of time and money. Have I "played" some DLCs though, yes.
