(man, she is though.)
The dossiers were top priority to me, of course. Just because I like to read as much lore as I can. ;P
Like, I'm playing Neverwinter MMO, and there's this city quarter that's overrun with devils of Asmodeus.
Except that a couple NPCs seem uncertain, suggesting that something seems off. And if you search out some hidden lore caches (and especially if you're a tiefling, according to the wiki) you get various snippets which together reveal that the Cult of Asmodeus, Lord of All Devils, the ultimate trickster... is getting played by the
Far-Realm. The succubus, who did the initial infiltration of a holy church, was never actually loyal to Hell but things from beyond.
And it's just a little disappointing that there's no in-game payoff for figuring this out. The hints become more obvious, until right before the final battle with the succubus, you get a lore update that basically spells it out. And that's if you miss the letter from a cult leader which basically reads "Asmobro, the succubus betrayed us, our brothers are deceived, send help!!"
You kill the succubus. Everyone's all "Ah, thanks for stopping the devils!" and sends you off.
For all its good storytelling, Deus Ex has a similar issue. It doesn't matter whether you figure out anything, the narrative is very linear until the last second. Though you can choose to avoid killing characters, at least (involving at least two "glitches", arguably). And you can even save a certain friendly NPC, if you negate his Agency
"I will hold them off for you!" "lol no"
