Can someone explain the reason of keeping the 'Gr.1-4' class system if Performance Points are coming back to GT7? Not mentioning how incredibly flawed it is in GT Sport and downright useless it can be, It seems like it would be less complicated to have event regulations combine PP with set basic vehicle categories like GT5 Lobbies had:
(example)
'NASCAR'
'Prototype'
'Open Wheel'
'Hothatch'
'GT Racing'
'Sport'
'Super'
ect..
At this point, it seems like the Gr. class system will only exist so Sport mode can have realistic grids of cars....
I think the current Gr. system should stay, but it would be greatly appreciated if we were often limited to a certain sub-set of cars within a class, and only seldom permitted to use any car within a featured class. For example, there were those daily races in GTS where you could only use the Group C cars within Gr.1. Otherwise, I think it's fine, and if anything, I think there's potential to add tons of more racers to all four classes - both real-world, and made-for-game, with the latter seeming like an especially good idea if licensing becomes a considerable issue. So for example, I recall hearing about DTM cars being hard to license, so I could see made-for-game Gr.2 cars being in the next game, especially ones based on models that weren't actually used in DTM/Super GT500.
I also think the PP system is returning because more typical tuning is returning, as well, and I think this'll be especially nice for addressing the issue of multiple cars in the same N-Class where one or two are clearly better due to their aerodynamics or something, such as how the Toyota S-FR Racing Concept dominated in N400. (That car could also really use a cockpit view - why not ask CALTY to draw one up?)
As for open-wheel racers, I think we'll only see one F1 car in a game at a time - maybe two if we're lucky - due to licensing. And at the same time, I think most open-wheelers are too different from each other to be in a single group, and not Gr.X. (The two SF19 cars notwithstanding, as I think they're ironically too similar to be worth creating a group for, wherein BoP would be potentially applied.) I cannot imagine a W08 going head-to-head with literally any other licensed F1 car that's appeared in the series, like the Ferrari F10 and 2007, or the Lotus 98T. More than one series of open-wheeler would be nice, however, like we can already see with the SF19 appearing alongside the aforementioned W08, so to build on that, I'd love to see F3 (perhaps Fraga's machine) and perhaps a modern Indycar, as the latter is already getting a Pebble Beach winner from the 1960s.
Finally, I had a very good idea where, in addition to the PP system and the Gr. system, there could be rulesets that are assigned for an event based on an event from the campaign. This would create a better relationship between the campaign and online play, as well as offer interesting rulesets and incentivize players to try as wide of a variety of cars as possible. The campaign would ideally include a ton of events from prior GT games, but also new ones, like a "Group C Championship," as well as revised versions of older events like the Sport Truck Race. (For that latter one, I'd not only hope that GT7 includes the Ford F-150 SVT Raptor and Toyota Tundra TRD Pro from GT Sport, but also introduces the Dodge RAM Rebel and the Chevrolet Colorado ZR2, as that hypothetical quartet would be perfect for a new version of the Sport Truck Race.)
