Yes. If a writer likes the look of a game you think is crap but they love, they will say so. Why is this difficult for you to understand?
Not so, my Vulcan friend. I don't know anything about Crysis, but Oblivion is the best game ever created in my opinion. You don't think so but maybe the guy who reviewed it did. I thought Fallout 3 was over-hyped as well, but I don't begrudge someone else thinking it is amazing.
Having a good PR team and bribing journalists are two different things (although sometimes the line between the two can be blurred). I agree with you that journalists are more inclined to score up games with big marketing campaigns and the like. But to say they are paid to do it by developers is 100% wrong.
I never played Witcher (why did they cancel the console version?! ) but if I played it and thought Oblivion was better, would I be 'wrong'? No. Because it's an opinion and it doesn't have to tally with yours.
