ok I give up, some people definitely do not have the same level of logical thinking that I expect from humans...
what you want me to tell you ? yes you are right ? If GT5 drop the 800 standard cars, the game deserves to score higher ?
I give up

we dont have the same method of reasoning...maybe we have different brain structures anatomy...
Look if your gonna talk about logical thinking than look at it from a reviewers point of view,
Here you have a game with THE BEST looking car models ever seem in a video game period.
As we have seen from previous GT games, PD have in the past had a relatively low number of cars in a game(compared to 1000 anyway),
Any reviewer(sane anyway) would give GT a great score if they had just got the 200+ premiums and standards were just some nightmare a GT fan had and never stained the game in the first place,
Then you give the reviewer a copy of the game which on the back of the box just says 1000+ cars and shows all pics of premiums and never says a word about the quality divide,
You as a reviewer would be somewhat peeved if upon expecting 1000+ equaly detailed cars(becasue nothing on the box has indicated otherwise) that you found only 20% of the cars look as good as advertised and many of the cars you want to drive are only standards and seem totally lacking compared to premiums,
Reviewers will not be reviewing GT5 for the likes of you and me, we'll buy it regardless,
Personally I counld'nt give a flying **** what a reviewer scores, becasue the only reviwer that matters for the game is me, and in your case you(I pressume).
But where it may matter is those who don't follow the likes of GTP and have bought the game or will buy the game based on a review, becasue contrary to popular belief around here, not everyone gives a damn about GT, and it aint the be all and end all.
So yeah, it seems wrong to give a game with more stuff a lower score than a game with less stuff,
But theres always that old saying of
"Quality ver quantity".
Maybe thats not 'logical' enough for you from a pleb like myself, maybe I just don't get it.
