Uh, some of you do realize that there are some things that the developers, you know, didn't think of when they first release a game?
If you're talking about games like SC4, or SF4, where you basically buy an "unlock key" to get the extra stuff, then sure, comments against DLC are justifiable in that case. But for games like Oblivion, Fallout, even The Force Unleashed where the extra content is released months - hell, even years - after the final product of the game has been finished and sold out to the masses, then you're just whining for no reason.
Like other said, if you don't want it, don't buy it. I'm pretty sure there's no one standing beside you with a shotgun to your head, saying you'll be having an extra orifice in your head if you don't buy the DLC for any particular. And if by some random twist of the fates you do, you have my hopes of you surviving the ordeal.
