Just to throw in my 2 cents on a few recent topics.
Damage - A lot of folks seem puzzled about the decision to gradually increase damage as the player gains more experience and gets to a higher level. For me, this is a far better and more elegant solution for implementation for many reasons. First, with regards to the GT enthusiasts and long time followers, it will allow them to adjust to the new changes. Granted, there are the hardcore who rarely crash or rub bumpers anyway, but there are also those who have played every game and still use other cars as "rails". Gradually introducing these changes will help them to become acclimated and, overall, become better drivers.
From the perspective of new fans and new gamers to the sim genre, it helps to gradually build their skill and teach them the basics of driving without instant punishment. If you hide the feature behind an "on / off" switch, then you're essentially robbing said player of the experience, IMO. By feeding them bit by bit you'll do better to teach them to drive, and teach them to use lines and overtake other cars instead of teaching them to use bumper cars.
This solution, for me, is much better than simply implementing something like a rewind or TONS of assists for players. It's obvious this is here to gradually make the game harder and ramp up difficulty, without making it painfully difficult from the outset. I say bravo, more games need to have gradually increasing difficulty (I may create a topic based on this, actually).
As far as reviews and what not, I think people are blowing it WAY out of proportion simply because this game has been much anticipated. I honestly believe that reviews are the least important part of getting a game to sell. Not to say they aren't important at all, but they aren't nearly as important as other factors. First up, word of mouth and hype. I think it's proven that games sell MUCH better when they have this astonishing word of mouth, and when their marketing campaigns are huge. CoD 4, for instance, wasn't a massive success out of the gate like MW2, or Black Ops. It took about a month for the game to really hit those absurd levels of sales, and it was word of mouth that did that more than reviews or anything else. Sure, reviews help pull in some early adopters, but the word of mouth sold it, and created a massive fan base.
GT, as a series, isn't much different. There will be a lot of people who will bite JUST because it is GT. The folks who bite and sell are the same people who maybe bite and buy Black Ops, and then sell if it's not like MW2, or Reach, or whatever else they want. This is a stigma of EVERY game. The blind buy always happens, and there are folks who give games a chance (or don't) based on their expectations. But for every 1 of them, there are 2 more willing to blind buy based on word of mouth or established appreciation for the series.
