Now for some worthwile comments by intelligent life.
For devil's advocate, the first 2 Fallout's have you go from town to town with the dot that travels across the wasteland automatically, with some random encounters and smaller areas in between to break it up. All in an isometric format so stuff like seeing structures like Vegas or instance off in the distance can't really happen unless it's in a cutscene or something. Compared to New Vegas which is kinda like sandbox in a 3D space in a "do what you want, where you want, how you want" format, I could see how the same environment wouldn't work between the two.
Exactly. Fallout and Fallout 2 work
exactly the same whether set in an empty desert or a busy metropolis, because there's a hub world that quickly takes you from point A to point B without wasting the player's time walking around nothingness. And unlike New Vegas' "Fast Travel", which one would think accomplishes the same thing, you
don't sacrifice combat and random encounters.
If I want to skip the boring parts in New Vegas, I will effectively be avoiding a lot of combat. My latest playthrough ended prematurely before saving President Kimball, but I must have fought hundreds of battles that I would have missed entirely if I simply fast traveled. Couple that with New Vegas' messed up Hardcore Mode, where fast travelling doesn't reflect real travel times (for instance, running from New Vegas to Goodsprings may take you 8 in-game hours, while fast travelling takes a
much shorter amount of time).
Fallout New Vegas' map to the south-west has a bunch of locations. From the little race-track to the ant mounts to the crescent canyon with all the gecko's to the crashed bomber plant to the little ambush site on the road. So it has 'stuff' in it. I guess the problem is that it isn't very interesting stuff and I'd blame the way ingame items and loot is handled in the game. Cause none of these locations are particularly interesting to come across.
This is the problem. The locations are just "names", so to speak. There's a little racetrack... with nothing. There's a crescent canyon... with gecko's and that's it. There's the crashed bomber... with nothing. It's nothing but visual dressing, hardly something to call content. In a turn-based tactical game, maybe these different locations could provide very interesting combat opportunities. In New Vegas, they barely make a difference.
Even in FNV it showers you in loot as you're 'constantly' being exposed to loot containers.
As well as this. In my last playthrough, the only time I felt like I found something "cool" was when I unlocked a box at Vault 34 which contained anti-radiation supplies. That was it. There was nothing along the lines of finding the Leather Jacket or the rifle at Vault 15, or exploring The Glow and finding a bunch of incredible equipment and loot.
New Vegas' map design is at odds with being a desert and being a fun place to explore. Thing is, placing a building in the middle of a road immediately draws attention to it and makes the desert feel less like a desert, because everything is cramped together. In the old world map of classic Fallout, you could easily do that without sacrificing believability. Whenever I encounter a random shack in New Vegas, my first thought is "in classic Fallout, devs wouldn't have wasted their time on this shit". And it's the truth. In New Vegas, Obsidian must have felt they had to fill in a quota.
These are basically the truest quotes about New Vegas:
Technically FNV isn't empty. But it might as well be.
As for the locations, well that was my argument. Whilst the landscape is constrained by reality and should remain a desert, the human infrastructure is in the purview of a sci-fi retrofuture, and you could invent whatever. Similarly as pointed out before and by yourself there's a lot of locations in Vegas that could be dungeons, but are nothing instead.
When you break down every single location in New Vegas and see what it has to offer, many of them could be cut from the game and nothing would really change. Once I've been to Crescent Canyon, there's hardly any reason for me to return there in subsequent playthroughs. I can't say I would miss most of the tiny locations, and if Obsidian had spent their time doing other, better stuff, New Vegas would have been much better.
Anyhow, these are self-evident truths which is why there's little point in continuing discussing them.
