wow. well said. I agree with you 100% on both God of War and Witcher 3. God of War had elements of both open world gameplay and also linear in terms of story telling. The characters were so interesting as well, almost all of them had an interesting backstory and the game approaches the Norse Mythology in a very unique and realistic way, especially the Aesir gods like Odin and Thor, they are so different from what we see in comics and television. Santa Monica have set bench marks with almost all their games, God of War 3 for the PS3 and latest God of War really pushed the limits of the PS4 with its no cut camera and almost no loading times, well the loading times were there but they were "hidden" in many different ways such as long boat rides and the long walks through the tree of ygdrassil. Imagine what they can pull off with the PS5's SSD, I'm so pumped for the next game!
As for Witcher 3, yeah your right there many weird bugs in the game and glitches but luckily I don't experience them as often as other players I know. It's interesting that you mention that the game made side quests interesting and worthy of completion, I think there are a lot of games were side quests just feel boring and like extra work, especially Assassins Creed. I agree the villains were a bit easy as well, especially the Wild Hunt like Imlerith, Caranthir and Eredin, those were such badass villains with great stories but they weren't that difficult to defeat. I guess the games scope was so huge they didn't have time to refine elements of the game especially towards the end but the game is still one of the best I have ever played. I liked how they used the soundtrack heavily in the game to, especially during freeroam the music really set the theme and emotions of the game, it reminds me of Ezio's Trilogy from Assassins Creed.
It might surprise you, but personally, after all that talk above, Assassin's Creed Odyssey is my best game, not as perfect as God of War, which was short to my taste, but ACO was the true successor to The Witcher 3.
Naval wars, conquest wars, the story, characters, history, your choices affecting the the end story, and insanely huge world. Most of the reviewers were "annoyed" because it's too big and dense, which is double-standards to me. Yes, most of the caves had plenty of recycled elements, but at the highest difficulty it was decently balanced and I don't end up killing a wolf or a monster like in The Witcher 3 with one punch! One of the most hated things to me, that difficulty curve, it's why I still don't like RPG's that much as a concept although they tend to be addictive but grindy.
There are recycled side quests that are quite repetitive but they're for who wants to continue playing, and there are main side quests that are very polished and well-done. Music was great, and I think music overall is a critical element in all games and movies/series.
I liked the sense of humor overall, and the balance between seriousness and silliness. I've finished everything in the game and explored every house, cave, mountain

The story to me was the strongest thing, and the history behind it and meeting famous figures like the funny Sokrates.
I'm biased towards Assassin's Creed anyway, although they have some flaws, but I love the history, mostly true history, behind it. But I liked it when it was against the Templars, the illuminatis, but seems they've manipulated Ubisoft lately

I've learned a lot from the franchise, and I still feel sad that it's not true to its main focus, but still love it.
