Gamers still havent learned that having fun has more value than graphics or being a technical marvel. Its the same reason why God of War won over Red Dead Redemption 2. Regardless of how much larger in scope RDR2 was compared to GOW, it felt like a chore to play where as GOW nailed its fun factor of satisfying combat.
No doubt Black Myth Wukong is a good game, but I'd be lying if I didnt say I get bored sometimes in between boss fights. Having side activities and NPCs to chat with, or even just music playing in the background actually does make a big difference.
