Game reviews are pointless.
How someone enjoys games is an incredibly subjective opinion, and tends to span over hundreds of genres which vary from person to person.
No matter how good you think you are at rating games, they will always be biased and the majority of people will rate them differently.
A better alternative is to just watch Let's Plays or gameplay videos and then decide whether the game seems fun. It's like a free demo. Game reviews offer no unique benefit over watching gameplay.
Tell your friends to stop wasting their time and pick up a medium of journalism that isn't a complete joke.
