4th would be more like f3 and less like NY, meaning generic rail storyline with distinguishable bad guys vs good guys, 4 dialog answer options and other stuff which is huge heresy in regard of classic games.
Graphic also look worrying to say at least.
My only hope is mods.
I actually liked the storytelling in F3 and NV. NV was just too linear IMO.
I am still pretty worried about the graphics, too. Not because they are bad, its just the colors, man.
F3 and NV had that typical post apocalyptic Fallout look. F4 kinda looks like Skyrim judging by the range of colors
