I won't bother listing games and sources as we all have some bias against certain sites because we think they are biased against our certain console.
The real question is, how many hours do they put into playing the game to review it and score it properly?
Sandbox games are not a game that you can "complete" so those are expection and one doesn't need to complete it to give a "fair" review. However, how many hours do you think is proper?
Meanwhile, games that require 15+ hours to "fully" complete, I think, are necessary for a play through in order to give a "fair" review.
I've read my fair share of numerous reviews. In most of them, they pretty much say the "caption obvious" things instead of the actual experience while playing. Did they laugh? Did they cry? How many times did they have an adrenaline rush dodging those hord of zombies? Did they feel attached to certain character after the game? They don't need to be specific in details. This gives me an impression that they spend about 2 hours reviewing the game instead of a play through.
