I suppose we have different things we call masterpieces. I'd give both 9 or 10 out of 10 (again, not far enough into Zelda to properly see how good it is), but to call something a masterpiece I'll not have anything to comment on as a negative thing, neither TW3 or BotW so far to me gets that notice.
I think what makes them both masterpieces to me are what they do, not what they don't. Witcher is just a ridiculous example of how to do story and characters in a game world, the atmosphere, the quests (bar the very tedious witcher gear ones), it all comes together to form something never really seen before on that scale. Sure it has problems with every part of it's gameplay mechanics for me, but that doesn't mean the whole experience isn't stunning. As for Zelda, well you are just getting your teeth into it, but man look at the world they've built...and I don't just mean the graphics or that, but look at how everything works together all the slightest of little touches that make it easily the most cohesive and interactive world ever seen in a video game. Sure the story is lame and the NPC's are bog standard fare, but my god the way everything works is just a ridiculously high standard that is going to take some beating. There's plenty of developer videos and talks on it too, how it's the new standard for world creation, which it rightly is. Just how Witcher is the yard stick for RPG's and how they move forward.
Nothing is flawless, it's just down to our own perceptions really. I think the problem more is when someone says "I don't get why..." then proceeds to bang on about their equally flawed game. We should just consider ourselves lucky we are still getting great games like these to debate about anyway I suppose
