Salt and Sanctuary (more for it being unpopular vs bad hivemind).
I love Metroidvanias, but combined with Souls-like elements makes for a very fun concoction. This one in particular I have so much fun exploring. The story telling and world building adds to the mystery and the fun of unraveling the story. It has a very good variety of enemies/bosses/items. It also oozes so much atmosphere. One of the better Metroidvanias (I played a fair number of them).
Another one is Dark Souls 2. I get it being disliked; can't be helped as it had a lot of departures from the first. But out of all 3, this one I played x3 as much. I absolutely love the sheer variety of locations (it's ridiculous); exploration is super fun and rewarding.
