Morrowind and FO N.V have more in common then any other thing I can think of. Oblivion hand held you like Fo-3 did.
By level design point of view ...
It is true that the quest characters seem more detaile d, more options ot answer better faction management etc but by the level design it's really poor ....
Most of the interiors looks like Dejavù of Fallout 3 , the exteriors are really crap actually , you do not have the feeling to be in a vast desert or in a desert at all , it mostly looks like the wasteland ....
Here is a picture of shoudl look themojave desert ....

now , this game fails at mainly the landscape feeling ... it feels liek a soprt of small place with some scattered stuff all around you turn and this pseudo arid areas with some cactus around ....
the buildings destroyed have no meaning to be since by the questline the bombs never reached this area .... plus the Actual way they should have done the very same NEw Vegas was something more like ....
This is how a Desert looks like with proper feelingin RDR , even if the game areas aren't that bigger....

Plus they couldhave added vehicles ......
I think that even myself coudl do a better job in this mod for oblivion , even tough it never was completed ....

The villages and city just look like clones more or less of the original Fallout places ... There is not really a feel of WOW ....
that's my opinion at least....
