Until there is a decent clutch simulation, what's the point? Other sims have a very good clutch simulation and and are better platforms for vintage racing. In rf2 you can LFB a 60's formula race car and never use the clutch- that is unacceptable and makes driving them no more than a semi sim experience.
Isi has a great platform for modern autoclutch cars, so they need to stick with what they are good at. I'd rather see them fix the cars they have and put on the back burner any cars that actually use the clutch until the company figures it out. I'd like to see more modern autoclutch cars.
