I really don't have a problem with DLC in most cases. Does it suck that we're paying for stuff that used to be part of the games? Sure. But the only reason why we didn't pay extra for some of this stuff is because there wasn't a way to monetize it before. Some companies do it better than others. I'm guilty of buying the costumes for SF IV, and the way Capcom did that was pretty crappy, considering that you couldn't just buy the costumes you liked. I'm stuck with a cowboy version of Ken because I wanted the Japanese fisherman outfit for Ryu, for example.
You guys are way off base with Asura's Wrath. That's simply a matter of when Japanese marketing gets confused. The game has a satisfying, conclusive ending. There's one plot thread left hanging, but I considered that the hook for a sequel if they ever do one. I'd much rather get more Asura's Wrath now via DLC than wait for a sequel that will probably never come. Same thing for Alan Wake. That game did post release content better than pretty much anyone. There's no reason for Remedy to make a 60 dollar disc release to a commercial flop. But releasing an episodic sequel via DLC directly to the people that want it is a pretty awesome possibility.
We complain about DLC a lot, and it gets oh so tiresome. The simple fact is that it's still a new thing and people are figuring out how to implement it best. I expect all of these things to be worked out by the time the 8th console generation comes around. It should be mandatory for people to be able to purchase DLC from within a game with little to no break in the action.
