New Vegas had elevators, too, if that's what you're into (and, wut? why would anyone be into those??)

Why aren't you into those?

Weren't those just loading screens though? Plus those were normal inside elevators the view from the upper deck of diamond city is nice.

I found Diamond City rather underwhelming shortly upon arrival and I find New Vegas prevails over it for a lot of the reasons JHE has already mentioned. New Vegas played a significant role in the plot and had plenty to show for it with the many conflicts revolving around the city that Diamond City overall lacks besides the paranoia behind the synths and the Institute and that are shared throughout the entire Commonwealth anyway.

I see Diamond City within the same areas of quality as a lot of settlements in Fallout 3. A settlement that takes place near an nuclear warhead, a settlement that takes place in an old hotel, a settlement that takes place on an old carrier, and now a settlement in an old baseball field. All settlements with a significance that only revolves around these novelty locations they live in, but no amount of depth in what goes on within these settings. I would say the only exception being Tenpenny Tower that deals with actual conflict and even has a quest that can change the settlement drastically.

Overall, I find NV far more compelling in what it has to offer over Diamond City. I'm not even quite sure what I think of Diamond City compared to Fallout 3's settlements. I'd say Diamond City has more style over them, but Tenpenny Tower surely has more to it in substance.

One thing I'll say though about the Commonwealth overall, I love the crime family background it has. Takes me back to what I liked so much about New Reno and New Vegas. Anything involving that is something I will always enjoy in Fallout. And I'm loving it in Fallout 4.

Just kidding. I love staring at four walls during a long loading screen.

Diamond City is basically Megaton.The city of New Vegas is larger and offers far more content, interesting characters, and factions.

I think Diamond City was disappointing.

It's a nice place, truly, but the later BOS and Institute locations are much-much cooler.

Albeit, I can't think of anywhere in Boston you'd make something like New Vegas.

It seems more alive to me than the Strip. Though the Strip had a lot going on indoors. In Diamond City when you're walking outside you get the feel of a functioning settlement whereas the Strip always seemed like a collection of buildings to me.

They both have their ups and downs I suppose.

All the Stands are wasted real estate.

I think that's where the rich people live.

Which....is just depressing, really.

Ugh. Don't get me started. I can't tell you how many times I literally FELL ASLEEP while playing Mass Effect and riding in the interminable elevators.

Full disclosure: I am old and fall asleep easily.

edit: Oops... to the OP. I like the comparison someone else made to Megaton. Better than Megaton, but not by leaps and bounds.

It's not a really fair argument, since New Vegas had engine limitations.

Diamond City looks really nice though, not exactly as advanced as it looks from the outside, but still nice.
