If that's the case then I can certainly agree! Deus Ex and NV have some truly next-level quest design in this respect. I can also see why you would cite the Witcher, in particular. Geralt has so many tools at his disposal, at least as many as the protagonist of every Deus Ex game and certainly more than the protagonist of NV. The linear ways he's required to tackle most of his quests while having all these options (talking things out, sleuthing, combat, magic both offensive and manipulative) makes the game's options feel weirdly claustrophobic at times.
If I'm getting you right based on your expansions throughout the thread, it seems like you're asking for more natural and diverse ways to tackle any given problem and I have to agree this would be a perfect fit for the Witcher and an easy way to make even simple quests more engaging specifically from a gameplay perspective. This is especially true for a game that's already sacrificed a degree of linear cinematic nature by going open-world, since it already emphasizes exploration and freedom. Why can't Geralt Axii that random mook guarding a door to get by bloodlessly? Why can't he sneak up on that villain to get a surprise attack in?
You should also play the Deus Ex series at some point. It's exactly what you're asking for, I think you'd love it. If you can stomach old graphics, classic Deus Ex is a treat, although I also really enjoyed the newer games.
