The naysayers are out in full-force @ GTPlanet!
I feel like half of the people on this forum read the IGN review and never even played the game!
What people are forgetting, or maybe not realizing, is that GT has transcended the video game format. GT is now a full-blown "simulator." Yes, the "career" mode isn't "scripted," that's what I'm assuming people wanted. Instead the career mode provides races for those without internet connections for online gaming. So what if the AI isn't all that tough, GT still provides one the opportunity to drive amazing tracks with amazing physics with car's the average person would never have the means to drive. The scope of the game in unbelievable. Has anyone done the Moon Rover missions? Those missions blew my mind. Looking back on previous releases of GT, I still can't believe KY included that, or even considered to include that in the game. Also, look at the ties GT has to the automotive industry, that displays how relevant the game is to a much larger industry than video gaming. And look at the launch party that the game had in Spain... What games have ever taken over a city for its launch? That shows you how important the game is to Sony.
Perhaps there are alternatives on PC that might "feel" better, but a lot of people aren't shelling out $1K plus on a computer, then buying a premium wheel, for a game that costs a monthly fee.
As for sales... Remember that this game has been out for four days! People have crazy expectations! Let's just wait until December is over and then we'll see!
