So if you were to write a review of the game you would say its not as good as Dishonored because thats what your opinion is, some people will feel differently, and that is ok.

The idea that a review needs be a completely neutral explanation of what a game provides with feedback on how well it performs that everyone will agree with is not possible or logical because we are all different. This is why sites like Metacritic exist but even then you can see it is a clear spectrum of individual views.

A good idea is to find an individual reviewer or site that has similar taste in games to yourself and follow their material if you want a clearer idea of whether you will enjoy a game before you buy it.
