For me Pcars 3 went from 100% simulator, to the Forza/Gran Turismo category. It is definitely not like GRID.Considering the fact that GRID exists (and is quite fun in its own terms), I resent a bit that people are quick to throw PC3 into the "arcade" category. It's true that the game is simplified from PC2, but it still has depth. Try to throw the cars around like in GRID and you won't make it pass the 1st corner of practically all the tracks in PC3.
It is quite fun, but for me career mode feels a little bit dull. Maybe when i will unlock more cars it will be more interesting.
Is it just me or AI with Aggressiveness on medium is definitely too agressive? They punch me like in Wreckfest. I will play it on low probably.
