Of course Fallout 4 will not outsell GTA V. That game sold more copies than NV and 3, combined. No game will ever outsell the GTA series. As for it being better than GTA V, I doubt it. Then again, that game is not as fantastic as many people claim it to be is because it suffers from three dumbasses as the playable protagonists, dialogue you would find in a Call of Duty lobby ("fuck you", "fuck this", "fuck that", "fuck, shit, dammit"), forgettable storyline, and gameplay that is inconsistent with its realism.
The Last of Us and TONS of
South Park and basically ANYTHING on HBO for that matter (not to mention countless other great sources of writing) would care to have a word with you over your
reckless labeling of "fuck" equating to poor dialog. The words, "Everyone, fucking except for you." get me choked up every time I hear them, and the "fucking" was KEY to what made it so good. Why? Context. The character in question swore a lot, and it was very endearing of the character. Just because dialog is swear-heavy doesn't make it bad. In fact, used properly, it tends to elevate the quality of writing. Because these are not writers treating characters like some kind of fantasy sterilized child's idea of a person who speaks in squeaky clean waxed poetic, and let's the person they're speaking to finish their sentences before they interject, and the sentiment is reciprocated. Nicer characters are often dull and simply infantile and unrealistic. Gruff, even nasty characters, just come off as more believable, and as such, more relatable.
Likewise to the assertion that the three protagonists were little more than "dumbasses". Flawed, absolutely. Dumbasses? Uh... no.
The protagonists in GTAV were INCREDIBLY well-fleshed-out, relatable, likable characters, each in their own very distinct way. In one act you might feel more for Michael than you would Franklin or Trevor, and the reverse could be true in another act. Each had their own distinct character and likes and dislikes and their own boundaries and limits, and this was successfully conveyed over the course of the game through both their actions AND their dialog.
So what if the word "fuck" was involved much of the time? It made it BETTER, because if these killers, who at some points in the game were literally pointing guns at each other and threatening to pull the trigger DID NOT say "fuck" in a great deal of their desperate circumstances...
that would just be sloppy, lazy, stupid writing. Because when death is staring you in the face, you don't stop to consider how many times you just said the word "fuck" in quick succession, much less tone it down a notch.
