I think it's the opposite of streamlining it. Because of the change in format it means that there's no reason to move the story along through encounters the way the game does. Something Neil spoke about in a recent interview is that Craig made the call to only keep the violence that's "very essential". That of course will heighten those moments in effectiveness when they do hit.

It also means that we spend more time with these characters and they can flesh them out more. And the relationships in the series is ultimately its heart. Expanding on that is something that even longtime fans can appreciate. They've also talked about some spoiler-ish stuff that would simply be impossible to pull off in a game, and it's something that will absolutely make effective use of this new format.
