The thing I love about these people is how they put down a game such as MGS4 for example when they haven't even played it, and it most cases don't even own the console it is on, and it's not just people doing it to PS3 games, same thing happens on all of the consoles.
Sure everyone is entitled to an opinion, but to totally slam a game or console you haven't played or owned is pathetic.
I never comment on a game unless I have played it, and I usually give it a proper go before I comment (e.g. BF:BC). I'm certainly not a blind fanboy who spreads lies and slander for no reason.
