The problem with reviews are that they’re an evaluation of something based on a certain set of values that the reviewer believes is important, but the values an individual reviewer (or collection of similar reviewers) generally do not reflect the values of the market on the whole.
Videogames are generally reviewed by a very narrow demographic of gamers who hold very similar values, and these values are often the opposite end of the spectrum of what the general public values. The obvious example is local gameplay vs. online multiplayer. Since the mid 90s videogame reviewers have (generally speaking) docked games heavily when they have limited/no online multiplayer experiences while not being particularly critical of games with limited/no single-player or local multiplayer experiences; and, being that few gamers ever actually play videogames online, it appears that online-multiplayer is actually not valued particularly heavily by the market on the whole.
