Again, it is a vague statement. Yeah sure he goes for 100% in all aspects of every game, but (and this is where the PS2 bit comes in) he was limited by the PS2 hardware whether he said so or not. He, and his studio, would never be able to simulate real life like a modern sim because the PS2 is incomparable against the later consoles, not to mention PCs (the main platform of sim racers) so you'd have to compare it to contemporary games on the same system rather than any PC based sim to get a fair result. Something you don't seem to want to do.
You'll be able to use this line of reasoning on
every single iteration of GT. No game will be able to simulate real life, current games included. You're really reaching to defend GT4 here - and the sentiment of that game having some physics issues is not a new one. A few of us have had issues with that one, that have otherwise enjoyed the rest of the franchise.
@Tornado and
@Wolfe both come to mind first. Not comparing it to current games either, but comparing to other early-to-mid-naughts ones. Enthusia did things better, and in some ways, so did GT3. Heading over to the PC, the F12k2 mods of the day were better, Nascar Racing 2003 was, and of course GPL, despite being barely younger than the first GT.
As for my vote, it's a toss-up between GT6 and PCARS. I haven't played AC or iRacing so can't comment on those two. NFS has set the bar low for the past 10 years, so I can't really be disappointed by that. GT5's long gestation didn't have me building it up pre-release, either: I expected it to have issues precisely because PD seemed to fumble with it for so long. Conversely, GT6 was a disappointment, because after three years, we were sold on the idea the second game on the PS3 would fix a lot of issues. I saw Kaz in NYC a few months before release and really believed GT6 would be a return to form. Instead, it was plagued with new issues in addition to carrying over some from GT5, or in a handful of bizarre situations, actually brought back issues from the early days of GT5 that had been fixed!
I had my personal issues with GT5, but I played it for quite a while. GT6, sadly, was played less than any other full GT title I've owned.
PCARS, on the other hand, has just been a disappointment. I'm not seeing what others see, I guess. Admittedly, I'm on what seems to be the worst platform (XB1), but I just have not got along with it. Admittedly, my tastes lean more towards road cars though. And it does have a superb track list.
