I am at a bit of a loss as to why "streamlined" is considered a dirty word. Fallout 2 was more streamlined that Fallout, yet it was entirely a PC game. Streamlining and dumbing down are not the same thing. Any developer looks for ways to streamline their games. I would prefer it if the streamlining removed only the more cumbersome aspects of the design and interface and left the complexity, meaningful choices, and significant consequences, but that doesn't always happen. It remains to be seen if Bioware is successful in doing this with DA, but it looks pretty promising thus far to me.
