Not every game needs to be open world. Nor does semi-open world equate to a lack of scale or immersion. I think GoW pulled it off really well, and I enjoy getting familiar with a location that isn't massive like, say, Witcher 3, but also not as confined as a Deus Ex. From the looks of it, The Outer Worlds is going to be a nice in between size world, but that excites me, because it implies that more time could be put into content/quests/world-building, etc. The Witcher 3 is one of the few games that I felt managed to make its side quests feel fleshed out despite the world map being absolutely huge and overwhelming. I'm pretty sure there are large portions of the Witcher 3 that I haven't even seen because eventually I just got too exhausted by the size of the world, and began to focus more on the story than exploration/adventuring.
