While I agree we shouldn't be locked to a car/class in nations, I'm also in favor of more creativity in terms of combinations. Wednesday race is Gr.3 at Suzuka and guess what, we already raced that combo in the first stage. Gr.2 at Fuji? Twice, not counting when it was in daily races (Although my only win this season was there, with a Days of Thunder pass in turn 1 when everybody in front of me crashed, and I went from 6th to 1st

).
Unfortunately, the combos when broad open become a race of marked cards. N500? X-Bow vs F50 vs 911. N400? count the S-FR Concept. Gr.4 with ridiculous tire wear? Alfas vs Megane vs Toyotas. We don't choose the car that we feel comfortable with, or the ones we like to race, we choose the few cars that can be competitive in an unbalanced combo. Many cars were added to the game and they would never fit in those races, so why keep adding them to a E-Sport driven game? I know, we could always have fun offline (I do, especially at the Nordschleife when the cars are added) but this isn't the mainly revolutionary idea of this title right?
My idea would be similar to what MIE1992 said, thematic races or with selected cars, not necessarily provided. PD already tested this in daily races and it was fun right? They have the data to decide whether a track is suited to balance the field, and with fewer cars they could created a One Round only BOP. I didn't tested these ideas, but imagine those races:
- Trans-Am Race: Camaro, Mustang Mach 1, GT350, Challenger ; (Future Muscle Cars if added) (At Willow Springs or a future US Track).
- Group C only race.
- Gran Turismo 1 or 2 Japanese car race (I hear Tsukuba? XD).
- TCR: FWD Gr.4 cars (Renault, Scirocco, Audi TT and Peugeot).
- An Italian Gr.3 race at Monza: Alfa Romeo vs Lamborghini vs Ferrari, or ADAC GT Masters, with German Gr.3. Of course it could be American only, British only and also with Gr.4.
- 4x4 Gr.4 Challenge (or maybe Subaru vs Lancer, someone remember TOCA Race Driver? XD) .
- Exotic race with Lamborghini, Ferrari, Aston etc, maybe N600 or N700.
- Something like the World Championship 1975 Class GTO from Rfactor: Porsche 930, DeTomasso Pantera, Corvette C3, Ferrari 512BB, plus future cars if added, example Ford Capri, BMW CSL etc.
- Other classic combos using for example the Toyota 2000GT, Jaguar E-Type, Mini Cooper S, Mazda RX500, Ford GT40, or even if provided the Alfa Giulia GTA, Ferrari 250, Jaguar D-Type or Aston Martin 1953 etc.
- Hot Hatch Cup: Focus vs Civic vs Megane vs Golf and so on:
- A Kei Car race, why not? Classic (Sports 800, Honda S800) or modern.
- A Road Car Edition race (Lancer, Alfa, Mazda, Mustang, Corvette, Atenza, Subaru).
- For the Final Round with the Top 16 race, maybe then a provided car with the Gr.X Unicorns, wouldn't it be fun for GT Youtube Channel to stream a race with Ferrari 330 vs XJ13 vs Mark IV vs Cobra Coupe etc in Goodwood, instead of a repetition of other races?
- Of course some rounds with unlimited Gr.3, Gr.4, Gr.2 and Hybrid Gr.1s.
All of these weren't one make races, you could always choose which car you want to drive, feel comfortable etc. Of course, the tires should be chosen accordingly, and it would avoid being boring.
If you want a one make race, there is also the possibilities:
-Renault Megane Trophy (without the nerfed BOP!!)
-Renault RS01 Gr.X Trophy car (I don't remember being used in an official championship yet)
-Porsche 356/A
-Renault 8 Gordini
-Karts
-Super Formula
-Mercedes F1
-Red Bull Junior, or X2019
-F1500
-Zonda R, Vulcan, McLaren P1 GTR
See? It wouldn't remove the possibility of racing what you want, but at least there would be a broader variety of experiences. And I know many of you could create similar unique combos like those.
