God, that was an amazing story. It actually had elements from all of the Fallout games. You had things like Tenpenny Tower from Fallout 3, and alicorns were basically the Super Mutants from the first game.stringtheory said:this is not to say that I've no exposure to the universe, I had have some through the longer-then-War-and-Peace My Little Pony crossover fan-fic Fallout: Equestria, which I think is a crossover of Fallout 3 (not sure though)stringtheory said:Well I've never played a Fallout game before

As far as Fallout 3 vs. New Vegas, it depends on what sounds more interesting to you.
If wandering a barren wasteland, killing raiders and mutants, scavenging "dungeons", and climbing mountains just to see what's on the other side appeals to you, then go with Fallout 3. Think Oblivion with guns.
On the other hand, if you want a game with a more solid story, interesting characters, good writing, and plenty of grey morality, check out New Vegas. It still has the exploration and scavenging from Fallout 3, but it isn't really the main focus like it is in that game.
If you're planning on playing both eventually, get Fallout 3. New Vegas has a few quality-of-life improvements that will make going back to the third game difficult.
