It's like I never played anything similar. I started on consoles with AC and PC and it was OK. You could slide sometimes and it was OK. But in rF2 you don't need to care too much. It's like you said about iRacing and rails. Every game is like on rails against rF2 to me. I can play with slip angle so much more than in any game. And almost everything is catchable. That's crazy to me and I love it. Hard to say how real it is.
I like something like GT3 and road cars. Almost everything is similar. New Formula is the best formula I played, it's so cool with this kind of possible "sliding". Everything is so alive because your input is always there.
You can't slide cars in R3E now. You can catch really small slides but everything else feels like scripted movie. You lost grip and only can watch 5 seconds of a movie. No input allowed.
Agree with iRacing, I discuss it with few people.
I like AMS1 too, it's like rF2 in some ways. AMS2 is sometimes rather easy and it's mostly strange. Feels a bit like AMS1 but with strange ME behavior. I am not sure they will build something consistent around ME. AMS1 was so good to me. Maybe next AMS will be on "right" engine
