GT Legends 2

I was having a potter around the interweb net and I found a couple of bits on GTR 3 and GT legends 2 and it got me wondering about the halcyon days of sim racing GT Legends and GTR2, and what we have today, awesome graphics and seemingly very little else in the way of SIM'iness, I have tried some of the latest offerings and, to be honest, I'm not really impressed with the results of a decade and a half of advancements.

So I ask, what, if GT Legends 2* ever gets created would you see as perhaps the most important area of the SIM?
Would it be
A: Graphics
B: Physics
C: AI
Would you go equally spread? or would you have the balance tip more one/two ways and not really be too concerned about the remaining area?
Perhaps there's something else that you'd rather a developer spent resources on?


*note here, it might not have to be called GT Legends 2 or even be made by SIMBIN, it could well be called 'Priceless' or 'Revival Racing'

B and C are the most important but as you say from first lines A sells games...

Obviously all three. Tried every racing sim out there keep coming back to GTR2.
Why: Good drivability, good graphics (although not up to project cars quality) and modifiable Physics, unbelievable amount of cars and tracks, the one area not so good is the AI but because of the other reasons above for me its acceptable.
