For me, when it comes to looking over what game I want to add to my collection next, the last thing on my list of things to do is check what the gaming reviewer from whatever website thought about it. I much prefer gameplay videos (I suppose that can be a form of review but still). I consider reviews to be a personal thing, and as such, are opinionated and personal. Who's to say Mr Reviewer will love the game whilst I may hate it?
Naturally, I don't tend to read them or take notice. What about you? Do you take notice or do you do your own thing?
