For a "real driving simulation experience" as Polyphony claimed, both GT5 and GT6 were disappointments when it came to realistic handling of cars and sounds. This is why I was so glad to see Project Cars, Assetto Corsa, and DiRT Rally go to the PS4. That's how handling (and visuals) are done boys. Most of the cars felt exactly the same with the only difference being two-dimensional speed and turning capabilities (and even the sound was similar).
The only good thing out of them was the online gameplay was fun and the weekly challenges were fun. When one can play a racing game with a hand-held controller better than a steering wheel, it's not a real driving simulation experience.
