This photo shows a race I've just been a part of last Sunday night. Spec Racing Club's Coffee Break races usually involve PP, tyre, power and/or mass limits, but otherwise is a free–for–all, and I really love the sheer amount of options the game gives me to meet those regulations.
To me, Gran Turismo's identity in the racing game market is that it's primarily focused on road cars. It's a very special kind of joy I can't describe when I see a car I've driven IRL appear in the game, and more importantly, it's the only game that lets me race SUVs, supercars, concept cars, and racecars on (roughly) even footing without the hassle of mods, and there is always a healthy player base for this kind of shenanigans to make finding races and clubs easy. I wouldn't want GT to change that for anything.
While I don't find joy in driving a C-HR in GT7, I do very much appreciate its inclusion in the game. The liveries people make for zany cars like the Carry and Hiace are a genuine joy to browse, and having a Prius in the game helps me better appreciate just how awesome a Supra is, for instance. I think a lot of folks here are already severely desensitised to speed in GT7 due to Sport Mode putting so much emphasis on racecars, resulting in claims such as the NSX-R '02 stops poorly, for instance. I think if GT7 were to feature only cutting–edge hypercars like The One:1 and AMG One, those ultra–fast machines would lose their sense of speed and what makes them so special, because there would be no context to their capabilities.
Would I love to have an Agera or a T.50 in GT7? Hell yeah. But I also think it'd be a mistake for GT to focus solely on a certain class of cars. I also want an AZ-1 and an AsparaDrink RX-7. For better or worse, PD is a very opaque company that is very selective about their avenues of feedback, and a lot of complaints from the community are still unaddressed as of today. I've always gotten the feeling that GT is Kaz's baby, and he's only sharing it with us, not letting us raise it.
