Good grief, this silly meme that "Fprza has more than 500 impeccable cars built from scratch by Turn 10" refuses to die...
Now now... the only person saying this is you, D
Now that GT5
is out though, and you're bringing up how both franchises recycle cars, I wouldn't mind seeing a car in FM3 (or FM4 in six weeks) that has been utterly unchanged in the model/texture department since FM1.
Then the comparison is the same.
Bringing back models from a previous generation, and improving them, is different from simply recycling. Some of the later Standards certainly hide their relative low-tech looks better than others (the new-to-PSP cars, as examples, but also things like the Celica ST185 Rally Car), but some of the cars that have been with us since GT3 really are starting to look sub-par in comparison to other games out there. Of course, the physics model is still present underneath them, but when it comes to really digging into the intricate details of cars, really revelling in the unique features in things like Photo Travel mode, well, that's where Standards sort of fall down. PD limiting people from even getting too close in replays hints pretty heavily at that.
That ties in to the main issue with having GT4's lineup making up the vast majority of GT5's roster, and the whole issue with this thread's original question; certainly a racing game shouldn't be about just the shiny newness, but GT5 is heavily skewed towards 2004 and older models, and has some large gaps for enthusiast metal moving forward from that point. Or, in the case of the oft-requested E30 M3, just strange oversights of older products. On the other hand - we got a good chunk of prancing horses as an introduction to the brand in the series.
Perhaps the real issue lies with the idea of a "car encyclopedia". While certainly a great one, and it's what's shaped Kaz' vision and the entire series, it's also the biggest stumbling block, as it will
never be enough. As modelling takes ever longer with each new generation, the time it takes to include new models will only increase, and there needs to be a line drawn as to how many near-identical cars are included. The average gamer, or the more casual racing-game players, are catching on - I've had numerous friends ask me about GT5's "real car count", asking if there's truth to the rumour of a high level of padding. So in that sense, I agree that GT needs new cars added - only to further increase its diversity, because those dozens of RX-7's, or 3000GT/GTO's, or R32-R34 Skylines, or Miatas seem to be at the fore-front of the discussion, ignoring the important fact: GT still does have the widest selection of cars in a racing game, even if you cut the above (and any other similar ones) to only 2 or 3 examples per generation. It's just that the reputation for padding can get in the way of that.
Whether it's the more appealing car roster, of course, is another, more personal matter, up to each individual. I say, to those who can do it... why choose just one game?
