I'd say the exact opposite. A great many FO3 locations had examples of visual storytelling. I have found very little of that in NV. In fact, the majority of buildings contain nothing but some loot. I found a train station filled with giant ants. Oh boy. Exploration was not the point of NV, as it was in FO3, and it really shows in NV. I found much of the locations uninspiring in NV. And frankly, as good as the quests (most of them anyway) and dialogue, they tend to be one shot content for me. After playing for about 150 hours, I have little desire to start another character because I know the story, have tried a few different builds, and basically, I have a strong feeling of been there done that. Unlike FO3, there isn't much point in exploring NV either. Wasteland mobs are few and far between. Locations are uninteresting.
I can see how many would like NV better, and it comes to no surprise that the NMA review praises the sort of content that their members enjoy, but I'm not one of them. I'm an explorer, and as one, I am a bit disappointed in NV.
I think this is what it comes down to for a lot of people. Some folks were annoyed that Bethesda "streamlined" the RPG mechanics from the originals (this did annoy me quite a bit...I sort of feel like they trivialized the RPG mechanics) and some were annoyed that they messed with the tone of the setting (this annoyed me a little, but I can get over it), but for the most part I do feel like the biggest divide is the quests/writing vs. exploration situation.
I totally get the people that enjoy Bethesda games for the sheer quantity of content and little things to find everywhere. I like that too. My biggest problem with FO3 is that I didn't believe the game world at all. Don't get me wrong, I enjoyed FO3, that was just a missing piece that was more important to me than it obviously is to others. The way all of the details, back-stories, dialog, inter-connectivity, etc. hang together to paint a cohesive picture of the game world in NV was a big deal to me. The fact that they took time to make sure that a variety of character builds are viable and character stats are more meaningful was a big deal to me.
I couldn't stomach a full second play-through of FO3 because I knew that all of the things that are most important to me were going to be pretty much exactly the same as they were on my first play-through. As much as I like having a bunch of stuff to find via exploration, it wasn't enough to make up for the things I wasn't ready to do again. That's just where my priorities lie. It's a little messed up for us to sit here and tell each other we're wrong for what we like, don't you think?
