Finished Alan Wake American Nightmare. While there was about as much story development as AC:Revelations, the new arcade-y gameplay is really fucking fun.
There's not really any plot development, but I thought it advanced the story a lot. Lots of hints at where the characters are now and other cool junk about the universe that's really, really important to learn about.
It's more of a filling-in-the-gaps story than a full iteration.
