Lately it seems that Horizon: Zero Dawn fits in this category. I love Aloy and I love the world that it takes place it, but there's just too much combat. I really don't like the way it handles, so even having notched it down to Easy to speed it all up, I still just loathe encounters in that game.
Another big one is The Witcher 3. It's a gorgeous game, with great characters in a great world. There's just too damn much of it and I have a really tough time just skipping a bunch of it so I can move forward with it. Again, the combat isn't my favorite, which really hurts the chances that I'll come back to it.
