Now, I'm not going to say which is better. I would like to make a comparison and contrast between the major elements of the games. The unique perspective on this comes from the fact that I'm just now getting into the first two Fallout games, but I got on board at Fallout 3 and New Vegas. I hope it puts a view on it not shaded by personal nostalgia. Anyone can voice their thoughts in a constructive way, and so help me if anyone knitpicks I will slap you with the deconstructionist argument so fast it'll make your head spin. Be forewarned, you will be getting some of my opinions, they might not be wholly right or wholly wrong, but I don't toss around my opinions lightly. Enjoy, if at all possible.
Spoilers abound, probably should play both games before reading this.
Setting
Fallout 3: Let me get this out of the way. Fallout 3 has the better strictly post-apocalyptic setting. Let's look at it this way. In both games you emerge into a town either Goodsprings for New Vegas or the ruins of another town Fallout 3. Which do you think has the most intimidate impact for post-apocalyptic effect? It has the ruins of D.C. which are a lot more compelling than anything in New Vegas with perhaps maybe the strip (a smaller area). However, I will admit that they are trying to accomplish different things.
New Vegas: It is society. The overwhelming motifs of civilization run rampant. You can't walk ten minutes (hyperbole) without running into some outpost, or some town, or something re-purposed as a town. It does give you the remarkable feel of society though. Factions, wars, and all the old-world problems. However, in terms of post-apocalyptia it scores low... because they've rebuilt. Not a bad thing, but not what someone would expect necessarily from a post-apocalyptic game just from looks.
General gameplay
Fallout: New Vegas: Yeah, it gets the gameplay section. Probably due to the fact that it's a sequel, but mods, Hardcore Mode, and a cleaner leveling up system puts it at the better point.
Fallout 3: It's good, it's very good, it was a good foundation for New Vegas to springboard, but once you play New Vegas it's kind of hard to go back to limited energy weapon options and no mods. (I've got a 360 folks)
Exploration and the main quest line
Fallout 3: I've got to give it to Fallout 3. Now why: Yeah, you had to find your dad, but you had to find Benny in New Vegas. What Fallout 3 does better is they don't twist your arm to get it done. You can literally go walk about just looking for stuff to do, things to find. On the exploration front they did it better. Sure the metro system is samey, but it's a metro system. A post-apocalyptic West Coast doesn't have the same allure to an East Coast at least for Americans. This is our capital, the second place we'd want to see is probably New York. That's how it goes, it might seem done, but that's what people want to see. Fallout 3 gives you the chance to explore a ransacked capital, New Vegas gives you New Vegas. Walking around the desert is not the same as the Mall.
New Vegas: Kind of flags here, the aforementioned arm twisting is mainly why. Anyone try to go north and get mauled by giant radscorpions? Did you go too far south and get mauled again. The game drops the not-so-subtle hints as to where you should go. In a lot of ways it discourages exploration. The terrain of the Mojave seems awfully more structured to me than it should be for a desert. Other than that it's got New Vegas to look at and Hoover Damn. No other real monuments or impact to be had from a kind of familiarity (again for American gamers, but would anyone outside of America feel anymore familiar?)
As much as I like New Vegas as a game, I'd rather have it in New York than Nevada, but this is to assuage the yearning for a sequel... which doesn't technically have to happen in the same region, but that's a different topic for another day.
Over-arching lore and Why?I personally, think (and this is where my nitpick warning really comes into affect) there is nothing devastatingly wrong in Fallout 3 to interfere with the first two games (most of this is second-hand from complainers). Why the East? Why not? Who said it had to be the West?
I'm sure someone will mention the GECK, but it's a MacGuffin go with it. Did it actually turn Arrayo into a paradise in Fallout 2? Was it ever shown working? Or was it just a propaganda pipe dream. From what I've gathered they're highly unstable. Maybe they just don't work like that. Certainly one of the vaults had to set it off? Sure not everyone had one, but hey. So if the GECK is so questionable blame 2 for it not 3. Still, that's a nitpick.
Fallout 3 has just as much right to be a sequel as anything. Again, nobody ever said it had to be the same place. However, this is probably why Bethesda did it. They did it to get new people in on the franchise. They didn't want to overburden them with back-story and lore. Go out, have fun, enjoy the world.
Bethesda did it to get a bigger profit. Reverse the order for a second and put New Vegas first. I know I'd be lost, but just the exposure to Fallout 3 and the basic elements of the universe prepped me for New Vegas. So they're not better, they're not worse in this regard. They're carefully planned.
I love both games, still play both, and treat both more or less as equals. I'd give the game-play to New Vegas in a heartbeat any day of the week, but in the story and narrative they both accomplish different and similar goals well.
