I've found that, often times, any reviewers who use comparisons of other games to describe to the audience what the current game they're reviewing is like, tends to lack an overall ability to convey original thoughts.
It's so much easier, and so much less work, to simply state that a game with similar graphics, in the same genre, is comparable to another game, rather than actually describing to the audience the strengths and weaknesses found in that game, alone.
