Something is wrong here, because this is patently untrue unless you only raced in the very first level or two and quit. Or only raced Arcade Mode. Also, the searching through "tens of cars," I've only had to run through two or three to get something competitive. If you went through twenty or thirty cars, you're picking through a pretty narrow PP range, and who's fault is that?
You are right though that A-Spec and B-Spec both are way too short, way too simple considering it's just the usual GT formula but with very few races. Some "series" are only one race long! And often, the tracks have little or nothing to do with the subject of the race. Even worse, out of the wide number of tracks available for events, PD chose only a select portion of them. Many tracks are completely unused.
Considering that Kazunori has begged forgiveness from the fans on a number of points, I'd say he does want to make amends in GT5 if he can, and definitely in GT6. I don't know if they're going to give us some simulation style pro racing in GT6 or some additional GT5 events, but many of us are asking. And just remember the whole rollercoaster of the damage implementation before anyone says that PD doesn't listen to their fans.
Jeepers, is this ever something I disagree with. Saying that Shift has a decent stat structure for comparing performance with your friends is sure a LONG way from saying they know how to make a good career mode. From what I gather, Shift's career modes are rather like Toca's, which is okay, but hardly what I call a great career mode. Likewise Forza, especially with F3's "choose your own adventure" path which is an extension once again of Toca's, and race 20 or so events when the "season" ends and you start over. Admittedly I never used it, jumping out to picking races from the selection grid in the order I wanted. They no doubt are much longer than GT5's "career" - Forza 3's 20 race "season" aside, use all or most of the tracks in the game, but really aren't much different otherwise.
Kaz could learn a few things from Forza, though mainly the excellent Storefront and Livery Editor which T10 tacked onto the GT concept. And frankly without them, Forza is just another racer to me. And they could look at real life motorsports more closely, of how racing careers are structured, rules are set, and stats are tracked. I would like to see a series of more real life careers in GT6, with rules from many types of racing, and this could run alongside GT and Arcade Modes so you could always go back to old school sandbox xtyle GT racing.
and getting a real buzz if you get a podium spot! That's what racing is about for me.
