I can share my perspective, which is that of a video game reviewer who also consumes a lot of reviews.
I want to be educated.
That means the reviewer tells me about the nuts & bolts of the game: mechanics, modes, scenario, options, etc. It might also include a lesson on video game history or culture.
I want to be entertained.
Whether through clever language, humor, or even sarcasm, I expect a reviewer to use his/her vocabulary and wit to wrap a review in entertaining prose. Anyone can list multiplayer modes and recapitulate a story; a good critic has more tools in his/her tool belt.
I want to be treated with honesty.
Reviewers should be honest with themselves and their audience. They should be consistent in their review criteria and independent of publisher/advertiser interference.
This is what I try to achieve in my writing, and what I expect from others.
