Hardcore sims are more and more a niche genre and, frankly, once you get to a "perfect" physics simulation level, they all kinda feel the same. Plus, all of them seem to be engineered towards this bizarre goal of proving that realism is an undrivable car on track, like if it isn't insanely difficult to keep it on line, it isn't a simulator. A few years ago I saw a discussion about racing games realism where Ben Collins was arguing that all games seems to try to make racing cars almost impossible to handle, where in reality is generally the opposite: they are "easy" to control, hard to master and find time on by most drivers.
So, I ask, another hardcore racing simulator on an already confused world?
I'd like more to see a even more polished game, fixing some design choices like shoehorning rally just for the sake of it since GT2 - if you won't do it properly, just leave it alone - a more diverse track hoster, an overhaul of the car classes so that they actually resemble real motorsport, a revamped career mode, hillclimb events and whatnot are much more feasible and - dare I say - useful features than going full on simulation in my opinion.
