While I have not personally driven a single seater or high level racing car, as far as the realism of iRacing goes, keep in mind that many professionals use it as a training and practicing tool. That alone tells me it’s probably pretty damn close. Not to mention, the entire purpose and intent of the creators is to make it as close to real life as possible in how the cars handle and behave. They go so far as weighing each individual part of the cars to make sure the balance is precisely as it is in real life (if they’re allowed to do so. I know in cases like the Corvette, Chevrolet wasn’t exactly quick to give them the info of every piece down to the gram of a car they still use competitively). And it’s continually being improved and adjusted. And now I’ll quit the realism tangent. X)
I agree with what was said above about making the 80′s equivalent of Grand Prix Legends. I would buy that in a heartbeat! GPL was terribly addictive despite the steep learning curve. And really, judging by how many mods there are of Rfactor for vintage F1 eras, I think it’s a safe bet people will buy it.
