Gundato: Again, they drop the prices of their games. Guess what? Gamestop isn't going to be selling something for 45 bucks if it is available new for 20 :p. I too wait for price drops on a lot of games, but that isn't really going to stop the used game market.
While I find some 0Day DLC to be questionable, you also have to keep in mind that it isn't (always) just a case of chopping things out. After a certain point, the art and level design people aren't needed anymore, since the game is being beta tested and patched. So rather than sit on their hands (or go work on a different game), they can work on more content.
Yeah, I definitely support their price drop policy. No two ways around that. :D I picked up a whole load of £5 games right off of their site, including Mass Effect and Dead Space.
My problem with DLC falls into two categories:
1. So many different versions of the game result and not one of them is complete. It just leaves me waiting for the GotY version of the game, even when I'd otherwise be tempted to pay more for it earlier on. Dragon Age is a perfect example. In fact, so is Mass Effect 2 now I'm actually enjoying the first one.
2. It's being used against the consumer like this. I don't know what kind of DRM they're using to stop second hand sales, but I bet this is going to cause just as many headaches for original owners as Microsoft's DLC DRM on the 360 does.
