I'm from the Vegas area, so I have to go with the Mojave.
Home, home on the wastes...

Think I'll go with the Commonwealth here. Not really a big fan of deserts, but the Mojave's a nice place, too.

Plus, I like the Commonwealth's atmosphere a bit more.

I enjoy exploring the commonwealth more than the Mojave, but the stories and quests are far better on new vegas

it's the same with Fallout 3, bethesda make brilliant maps, but typical generic quests and characters

i would have to say the mojave. I do like the commonwealth dont get me wrong but i dont feel like fallout 4 is a fallout game.

My heart will always belong in the mojave

Mojave desert for the win can never beat the cazadors or the gambling

For the moment: mojave hands down. But who knows what modders will do to the commenwealth and maybe some day the can stand as equals:)

i liked the commonwealth better than the mojave. its more cluttered it gives you a sense that people lived there.

To be honest as much as I loved the Mojave it was very unfinished and rushed, Freeside and Searchlight airport for example.

Love the atmosphere of the mojave, prefer the polished and cluttered commonwealth.

Umm maybe i will just go for the commonwealth just because it has the Boston theme and  its more i would say...
More settlements need help.

I Love the Commonwealth Map, but the actual content for New Vegas makes me sway to the Mojave

Mojave with out a doubt

I love the open wilderness feel of the Mojave, but the Commonwealth feels much more alive. I'd say I prefer the Commonwealth only because it looks a bit better being a 2016 game. The Commonwealth, DC and the Mojave all have their own atmosphere which are think are very cool and different in their own way.

Mojave is my favorite because it reminds me of home (I live in southern Arizona)

the mojave lacked a bit of things to discover... (no ruins like fo3). Fallout 4 has different biomes (glowing sea, swampland, the ocean with nothing in it and other stuff). So location wise I'd go for the Commonwealth

The Boston Wasteland Area is better to me ^^

The Mojave felt... Empty :/ !
I mean, in Fallout 3 for example, there were a lot of unique locations, each one was attached to a quest or at least had some kind of lore...

But in New Vegas, some area were there... Just to fill in the blanks !

Mojave for me, just doesn't compare to the commonwealth.

Definitely the commonwealth, I like the vibe of the mojave but it felt so small to me just because it seemed like a big circle, didnt feel like there was much to explore. Capital wasteland would be my favourite if that were an option.

most people seem to say the commonwealth, but I disagree. The Mohave was so much more interesting for me, each location was tied to a quest, or had something interesting in it. In the commonwealth, there are so many locations that are just bandit camps, or just have "Le funny skeleton meme", sure there are some funny or interesting locations like the office where the guy said he'd stab the lady with a pen, but we haven't gotten anything as unique as Nipton, primm, or caesers camp. All of those are unique because they either have an interesting visual style (primm with the roller coaster and casino, caesers camp simply because of the legion aesthetic, and Nipton because the whole town is in flames and crusified. All of them have quests related that are enjoyable for the most part, each has memorable characters as well. Fallout 4 didn't have that same feel, it felt tight, but it lacked substance. I'll take wide open with content over tight and empty.
