Famine
I don't want any car which doesn't have any competition - or rather if "x" car is in, then a competitor MUST be in.
Where's the competition for the F1 car? There isn't any - just another F1 which is identical (perhaps with colour variation). Same goes for the Escudo - it managed a slower sibling Cultus in GT2, but since then it's been on its lonesome as the only Pike's Peak car in the game. Note that by "competition" I mean a similar vehicle, not "something which you can beat it with", as a sufficiently talented driver can take on most cars with most other cars (as in the 2nd 9 Boards Challenge, where I was amongst others racing in Boombexus's choice of fully-tuned Integra vs GT1s on Seattle. 3 laps. No touches. It WAS possible to win the race), especially with GT's immensely monged AI.
The only possible exception to this are the one-off, curio cars. The Espace F1, for instance.
If there's an '04 F1 car, I want either distinct manufacturer variants of it (either real or "homage", realistic stickered or not) - Mercedes F1, Renault F1, Honda F1, Ford (Cosworth) F1 - or '03, '02 and '01 F1 cars. Or have a laugh and race the Tyrrell 6-wheeler, the BRM V16 and anything from Sir Stirling Moss or Juan Manuel Fangio. Same goes for Pike's Peak. We have the not-exactly-special Escudo Pike's Peak. Why no Audi Quattro? Citroen Rally Raid? Ford RS200 Evo2 Pike's Peak? Toyota Celica? All these manufacturers are in the game, so where's the Pike's Peak cars for the otherwise-lonely Escudo?
It's like going into a grocery store and finding they only sell one type of beer. You have no option. If you want beer, you have to buy that beer. If you have a choice, you may well go with the original beer, but at least there's an option to be wild and try something else.
I agree with that wholheartedly. GT3 offered us an array of F1 cars like my personnal favorite, the Mclaren MP4/4-Honda (F688/s). It saddened me to see it off the GT4 car list (the 1997 vertigo race car is dearly missed as well). In GT3, the MP4/4 had a nice set of competition, including the Williams FW16B-Renault (F094), Lotus 99T-Honda (F687/s), Williams FW11-Honda (F686/s) and the F090/s, (which I dont remember what car senna drove that year, was it still mclaren honda?).
All that being said, The need for an extensive list of cars is not yet present in the GT series. In GT4, you can race a Toyota GT-one, Toyota 7 and a Mazda 787B and still get a competitive race. The cars arent exactly realistic in performance, especially with the race cars. That eliminates the need for an extensive list of cars from the same year/series/era etc. (though it would still be nice).
For example, In GT4 it is quite easy to get a lap on suzuka in a late 80s groupC LM under 1'40 on relatively hard tires. At that same time, F1s werent close to breaking 1'40 even though it was one of the fastest eras in F1 (Turbo). Thats just wrong, there is no way a Nissan R89C should be lapping faster than an F1 of the same era. PD needs to fix this.
Easier said than done though. While PD has most probably driven the majority of the road cars in the game, I doubt they have driven the race cars. Most of the data gathering is probably from video and predicting. How PD could get their hands on the Gt-One road car is beyond me, and the Auto Union Streamline, uhg, yeah right.
While it would be nice, there is no need for alot of the same cars running together. One-make races are always quite fun, and Ive found that mixing LM, JGTC and DTM cars into one race can make for interesting battles.
Even if the grocery store only offers one beer, Ill take that beer and Ill also grab some potato chips, cookies and a few various donuts. All together, it makes a pretty good meal. If you dont like the beer, you can drink water instead. Why? Because Kazunori said so.
