How to write a game review?

Hi everybody,

So I want to write a far few game reviews and I started but I see that I mostly write words that would kind of sum the game up and then realize that my reviews seem the same.

I followed IGNs review score system how the sum up each section 'game play, presentation and so forth'

I obviously wanted to know if I was to post a review for a game that just uses IGNs review score system would seem incomplete without talking about the game.

Hard to explain but when I talk about the game I don't know what to talk about without talking too much.
