I'd prefer silence and minimal story, but if I have to put up with both to get a Metroid that isn't trying to be other FPSs (MP3 and MPH) but is more like Super Metroid, Metroid Fusion or Metroid Prime in its approach, then fine.
The story parts in Fusion are probably my limit - well done but not overbearing. The nonlinearity was quite bad, unfortunately Sakamoto seems to like it.
But if they add "other hunters" or "allies" or "fight alongside the Federation" then I am snapping my game disc in two.
