Hands down GT3 was the best. 4 and 5 are good but I feel things have been going abit backward since 3.
Another +1 here (except for the "4 is good" part). 👍
GT3 was my first Gran Turismo (the PS2 being my first Playstation), and it's the only one I enjoyed playing, period. It was an amazing game, and I became an immediate follower of the brand -- registered on this site in 2003 -- but Polyphony Digital has done nothing but disappoint me ever since. I can admit that GT4 and GT5 have all the trappings of an incredible game: an encyclopedic car list, a stellar track list, plenty of stuff to do...but you mostly do one thing in a driving game, and that's
driving. When it comes to that core experience, I think it's absolutely right to say things have been going backwards.
Now GT3 wasn't the most realistic sim in the world, but it possessed a certain handling balance that PD have completely lost. It was floaty and simplistic and kind of numb, but you could manipulate the car as you please, in a reasonably believable manner. Only Kaz knows why, but GT4 trashed that in favor of a brutally twitchy, understeer-biased model that punished anything resembling "fun." With GT5 they did a patchwork-type job on top of that, making it possible for mere mortals to drift a car again, but they left other things just as broken as they were in the PS2 era.
Honestly, I would rather that PD kept the physics exactly as they were in GT3 -- flaws and all -- than see them continue the hackjob tweaking they've been doing in the years since. It wouldn't make for a class-leading simulator, but at least it would be
fun to drive.
