I just figured something out. GT5 is like racing for dummies (I'm not being rude, I enjoy the game), because it's incredibly easy to drive any of the cars fast and to the limit, with throttle misuse the only thing that can get you into trouble. Think about it. How many people have been saying in 'GT5 they can jump in and set awesome times with most cars, but Shift 2 doesn't handle well at all.' GT5 is all about getting your lines right, because the act of getting through the corners in the first place is easy.
Shift 2 is difficult to race at the limit. You have to be smooth and precise (except the throttle is the opposite here and doesn't need as much care as it should) to do fast laps.
What is more realistic there?
It's very hard to unsettle a car in GT5 (wheelspin is not unsettled), in Shift 2 it's easy to drive, but hard to push as the cars get unsettled easily. Yes the bit of input delay is annoying, but if you drive smoothly it is hardly noticeable.
I won't have a final verdict until the day I stop playing, but for now I'm very happy with the game. The thrill of actually chasing down the car in first over a lap and a half while having the car on the limit and passing on the last corner is amazing and I really feel a sense of accomplishment for keeping the car under control the whole time! Definitely get the pulse racing
Oh and how many gamepad players went straight to Elite and turned off all assists, then complained about the sucky handling? Put steering assist on if you can't control the cars, it's there for a reason...
