I've been lurking around since before Skyrim's release, but I figured now's a good time for my first ever post.
Something that seems to be an accepted axiom, even amongst Bethesda fans, is that Bethesda are crap writers. The go-to example for a "well-written" game is New Vegas. Frankly, what constitutes "good writing" is so vague and subjective that there's hardly a clear marker of deliniation. But what's often repeated anyway, is "Bethesda's writing is full of cliches and New Vegas got it right."
Firstly, Obsidian bent this very basic rule of writing and it did it frequently: show don't tell. Much of the critical information of the factions, the world, the characters, and the plot (though not all of it) is stated directly as dry exposition rather than experienced naturally as a player. And some of what's told feels directly contradicted by what you actually see. So you hear New Vegas is a happenin' town, filled with brilliant lights and casinos of vice, and excitement and adventure? Too bad, it's dull, flat, uninteresting and lightly populated with NPCs with all the weight and substance of wet cardboard. So maybe things aren't black and white with the factions, maybe it's not clear good and bad? Tell me, who sounds better: a gang of pyschotic slavers who you personally see raze a town along with crucifying and slaughtering its inhabitants (who you only "hear" were not that great of people), OR a democratic republic with a firm and reasonable rule of law that protects the innocent and maybe has some bureaucratic troubles. As for typical tropes and cliches, New Vegas has them. The whole beginning of the game is a basic "revenge" tale, the driving force of the plot is an absurd macguffin (the chip, which can also constitute as the plot point for the first part), and main conflict is an obvious "good vs evil" (NCR vs. Legion). New Vegas is a great game, but it's hardly an inspired piece of Shakespearean brilliance.
As for Bethesda, though there's plenty of common tropes, they manage to create multiple conflicts of ideology where both sides have reasonable points (Evles vs. Men, Imperials vs. Stormcloaks, Reachmen vs. Nords). They still make plots where there's more occuring beneath the surface (especially if you're in tune with lore). People still argue and talk about plot points and lore from their games, even years after the fact. For such a "poorly written" game, it's quite a feat that there's still arguement about the civil war in Skyrim 4 years after it's release, even in communities outside of Bethesda's own.
S, I'm hopeful that the story in Fallout 4 will enthrall me, and that those who prefer lighter fare will still enjoy and understand the plot without having to think hard about what's below the surface.
