I agree Andy, I do use them as a benchmark however when deciding which game to buy (if not any of my favorite series)
I recently bought Infamous 2, Red Dead Redemption as I loved Infamous and have heard the greatest things about RDR!
I do agree with IGN most of the time as my reviews would be fairly similar, Demons Souls, finished it over the weekend, best game ever created (apart from MGS and ME) 9.4/10, I agree with everything they mentioned about flaws etc
Also, RE has seriously lost its horror/survivor mechanism since RE4 came out! Its more of an action game now, RE5 was cool but lacked any real scares, SH still manage to play with your psyche a lot better!
Might buy Downpour when it comes available on 2nd hand or something for like R199 (£20)
