Apparently the upcoming Broken Steel DLC will fix one of the major complaints about the game, the way the ending was handled.
Awesome - unless of course, you don't have access to the DLC. Actually, I see this as kind of a big jab with a pointy stick to all Fallout 3 fans. Bethesda is basically saying, "yeah, we screwed up - it was a pretty stupid way to end it. Now pay us if you want it better."
I get paying for extra content. But there's a more acceptable way of updating your game to fix stupid things that were done during development. It's called a patch. I get that Bethesda signed an exclusive for DLC, but why a) make users pay to correct a mistake and b) refuse to offer that fix for every player?
Update: Of course since this posting, DLC for PS3 has been announced...
