My impression is that reviews generally bring up points that are both valid and true and I understand their complaints. However, it seems like a lot of them have detracted a whole lot mostly because of rather the minor issues when they think the gameplay is world class and simply epic. Too much hype I guess.
I don't disagree with the reviews, I have played better games that GT5 but I can't say that I've played a better racer so I'm kind of torn. The idea of an 85 average score is fine by me but it also makes me scratch my head when I see utter tosh getting 9's and 10's sometimes (games like Crysis). There are way too many high scores this generation, I always end up disappointed when I try these highly acclaimed titles so I'm actually kind of glad that some have the audacity to treat a huge blockbuster with critical eyes, I just wish they would have done the same with a lot of other titles.
I would have given a score in the high to mid 80's myself to this title, I absolutely love this game! But it does have issues, not the glitches and minor flaws but sheer game design issues.
