OK, I'll try this one more time (please bear in mind that I have played GT5P
a lot, & while I'm not the fastest driver out there, I'm pretty decent):
after months of playing GT5P,
I honestly don't think you can appreciate FC properly after a few hours - I know I didn't. Yes, it feels quite "arcadey" at first - part of this has to do with the arcadey-looking graphics. Yes, it feels "unpredictable" at first - it takes a while to get to understand that the inputs you make,
do precisely effect your laps times. After 40 or 50 hours you'll come to know how slight adjustments to the steering, brakes & throttle effect your speed going into, around & out of each apex.
Switching back to GT5P after playing FC a lot, GT5P feels weirdly understeery - as though the car tires don't want to track at all. The "wibbly" feeling in FC is an attempt to model weight-transfer & body-roll, something the GT series has never done well (see GT4 vs Enthusia). In GT5P the car sits squarely on its tires until you push it too hard &, with no real warning, the car starts to slide sideways. You have to
learn though practice where the point of loss of traction is.
In FC you can
feel the car start to "lean over" its tires - the inside wheels start to lose load & the outside wheels start to "judder" (grip & release) under the increased load - ease off the throttle & you can feel the weight of the car move back from the outside & the tires regain steadier grip. That's the "wibbly". Move through a succession of corners, especially downhill, like at Spa, & you have to control that shifting around of weight & grip back & forth & find the right balance for maximum speed. FC models this much better than GT5P, IMO, but it takes quite a while to get used to the "wibbly" & learn to control it.
Yes, it's a much slicker, more big-budget presentation.
Yes, System 3 misrepresented the game (as opposed to PD who are so uncommunicative about their plans that it would be pretty much impossible for them to "misrepresent" themselves), but it has still given me (& continues to give me) a lot of enjoyment.
