The difficulty of controlling a sim like PCARS2 is a consequence of shortcomings in its analog stick steering, which is SMS' fault. Purists cry "blasphemy!" at the necessary input processing -- part of the problem with PCARS is that internally, SMS kind of shares that mindset -- but Enthusia proved you can mate more realistic physics to GT-/Forza-style steering control. It is much more tamped-down than PCARS2, after all.The problem with this is that you're cutting out a large chunk of people that would be interested in the scope and style of a Horizon game if it had the physics and the daunting wall of entry that comes with having sim based controls, and having to shell out so much money for peripherals.
The problem isn't the fact that we wouldn't be interested in a more sim-like Horizon experience. The problem is that it would only be played by a fraction of the people that are currently playing Horizon, and ultimately, that is one of the keys to Horizon's success.
Accessibility is fine; after all, things can be made optional and only the no-fun-allowed purists would continue to complain. I'm also okay with abbreviated braking distances, unrealistic jumps, that kind of stuff Horizon has been known for since FH1. My primary concern is handling dynamics/behavior. All I want is a game like Horizon that is more natural and intuitive.
Don't get me wrong -- I know T10/PG are justified in leaving it alone. I'm just one of a minority of players lost in the middle between less-realistic driving games and realistic circuit-based racing sims, where my wishes are overlooked on this side of things and met with hostility in a place like the PCARS2 subforum.
