I never played the former fallout so like everyone says I want to say New Vegas because for me fallout 3 and 4 are too casuals and although I spend a lot of time on it I prefer New Vegas for the story.

The very first Fallout is my favorite game by far. No other game in the series can match its immersive gameplay. Too bad it's a bit too short. Fallout 2 is second on my list. Technically it's better than Fo1 but somehow it doesn't feel right. It's more kind of spaghetti western in post-apocalyptic setting than true Fallout game for me. Fallout 4 would be third. Not a particularly good cRPG but very fun game for exploration and some shooting. I only wish the world setting would be more dark and gritty (like Misery for Stalker CoP). Both Fo3 and NV are garbage for me.

mine is fallout new Vegas it was the first one i ever played i still love it
because of ammo types

Fallout 3 would probably take the cake just because the setting was so gritty the colors were so well done it really made it feel like you were surviving in the wastes but i love 4 because the advanced mechanics it brought to the table. so kind of a stalemate mate between those two.

New Vegas is my personal favorite and I have more hours in New Vegas than any other Fallout game.

I'm currently am in the process of understanding how to play the older Fallout games (1 and 2), since I've been more used to New Vegas and 3.

Fallout 3 was okay, some good story elements, but I see it as inferior to New Vegas.

I don't own 4 yet, and seen some gameplay, I'm a bit mixed on some elements. I love the improved gunplay, the crafting system, etc.

The settlements are okay, but fucking annoying, especially since the amount of NPC settlements aren't as common. My biggest gripe is the casualization, I don't like the dialogue wheel option, the voiced protagonist is okay, the factions (other than the BoS) are just dull and aren't as interesting as the other factions seen in previous fallout games. It's still nice that you can fix some of the things 4 did wrong with mods.

So in my opinion: Fallout New Vegas > First 2 Fallouts > Fallout 3 > Fallout 4

Fallout new vegas has an amazing world , factions , storyline , and I fell in love with the western style.

My favorite game of the series is the fallout fallout new vegas. There are several reasons why this is namely the fantastic atmosphere that you can customize yourself by mods and the fact that the fallout new vegas in my opinion have the best mods from each category.

Ooh tough call, tough call.

I really loved Fallout 3, even with some of it's flaws here and there, it had such a great feel and plot to it. I've had great memories of Fallout 3, seeing characters coming back from it in Fallout 4 was awesome.

But the very first Fallout game I played was New Vegas and that is still a very awesome game. The very fact is we get to see how our actions effected Mojave Wasteland, that's one thing both 3 and 4 have not done yet. Like 4, we got to see few characters from second Fallout game, or in case of Cass family members.

Like Tom-Collingwood said, all Fallout games are so unique and wonderful in their own ways. But if I had to chose, I would go with Fallout New Vegas until Fallout 4 brings up a DLC that'll get my attention.

I have to go with new vegas. There is so much to do in this game. The lore is interesting. Awesome choices and especially the mods are much better.

But basically how the world of new vegas is was a main reason. Such a alive game back then

I think I will go with Fallout New Vegas on this one, by the reason that not only the concept and gameplay of it is better than Fallout 3 in my opinion, but also because it is highly moddable, so that it can be very easily adjusted for alomost every kinds of preferences.

My favorite would be fallout new vegas for a few reason.
1) the game had a great story many different options and alot of cool easter eggs
(side note) Fallout 3 had a great story to more than fnv in some areas
2) Great dlc well i will say that fo3 dlcs were great honest hearts and lonesome roads were amazing experiences for me.
3) this community, the awesome mods and armors released makes me keep coming back for more.

Fallout New Vegas for it's content, stories and characters

Bethesda should just make the game map, and then give it to Obsidian for everything else

Well the fallout with the best story has to be the first one and atmosphere .Gameplay speaking it has to be the Fallout 4 .Fallout 2 ,3 and NV lacks the Grim dark .You know when you enter the Masters bunker and everything is ...made out of meat and organic stuff .Whish there was more in the last games but we got Synths .But Fallout 3 and NV has that special place on my HDD .Those were the one i enjoyed the most .
Kinda whish they had Power armor like in Fo4 ,not the part where it brakes like an egg ,butt the one where you are a walking tank .
Cant have it all .

Fallout 4, I have played 3 and Vegas. But for me the newest edition offers a lot more potential, not because of graphics or anything but it's diversity. The modification system is going to allow a far more in depth look at modding in general, the crafting side of the game also adds to the experience as well.

New vegas just seemed like a rushed release, the feeling of the game was a real let down to me, the world seemed uninteresting, the function of the game seemed to lacking for what you'd expect. So in that regard I think FO4 is the best game, because it combines a lot of good features while maintaining that feel we have come to expect.
