Is it really that weird? Am I just some sort of clown ghost who appears here and there to make fantastical statements before vanishing into a cloud of silver and mystery shifting aetherweave?
Don't be childish. You know what I mean.
DA is defined by darkspawn vs everyone else, save the world from the big bad darkies, just like in Tolkien. TW is like you versus every other thing kinda just after your girlfriend and a bunch of strange mythical beasts and stuff, most people and things are shifty and unpredictable.
... I'm starting to wonder whether you paid attention to the story AT ALL. How does 'darkspawn vs everyone else' even apply to DAI for example? There's only one prominent darkspawn there, really, and it turns out to be a mutated ancient priest worshiping an unknown entity that led him and his team to a mysterious place invading of which scarred the world forever. There are factions, lost Thedosian history and ancient beings creeping out of the woodwork that have nothing to do with darkspawn, and you want to claim that it's "darkspawn vs everyone else"?
Also - this is the least flattering (and not exactly compelling) summary of what happens in the Witcher I've seen. "Stuff happens and a bunch of strange mythical beasts", basically.
When Ander's gets possessed by a demon, he makes friends with it and it's name is justice and he and the superfriends sing songs and have rainbow dances, but then he has his magical bauble of innocence shattered when he learns that the boo hoo lords don't treat his kind nice, so throws an angry tantrum and then comes whining to you about the consequences of his actions like a deer in the headlights.
You're acting as if Anders was the only one possessed or like he's the most important person/villain in whole DA, which is amusing. How do actions of one man (also summarized as uncharitably as it's possible) define entire series, exactly? It's the same with Baron quest - it's hardly something that deefines the entriety of TW3.
When someone gets possessed by a demon in TW, they become, you know possessed, their eyes turn red and their body convulses as some invisible unkown demonic spirit coerces the truth about the night in question where the man savagely beat his wife into a bloody pulp and murdered his child, before disappearing and you don't try to take vengeance, you try and work with the man to make amends, even though he's got questionable ethics.
Spoilers much?
Also - in DAI, your'e working with a former GOD that is trying to make amends for possibly destroying his own civilization and being in conflict whether he should bring the remains of it for a cost that's probably enormously high. What about Blackwall - a soldier that killed family for money?
