All reviews are subjective by definition. Your examples are observations, not reviews. A review is my opinion of the product based on my experience. Like honestly, if you ever wrote a review about anything on Steam, or IMDB, or GoodReads or whatever, go find it and remove everything that’s subjective and see what you’ll end up with. Not like you’d be able to post it, because they require you give a score, which is inherently subjective.
