Hey, I know there are some sim racers on here..
Assetto Corsa just came out with a Japanese car pack a few weeks ago that includes a 370Z Nismo (latest edition) as well as some other great cars.
It's definitely the closest thing to driving a real 370Z on a video screen. Though the Nismo obviously has different suspension than my sport package, I was really surprised how many things translate so well between the game and my real life driving experiences in my 370.
For those not in the know, you may be asking "How is this news worthy? The 370Z has been in Grand Turismo. Forza and other racing games for years".
Well, Assetto Corsa's simulation of real world physics is miles ahead of any of those and some other similar titles, you can be sure when they add a car to their title, A LOT more attention goes into it than most other games out there.
RFactor 2 also has a 370Z and I know that is also a top tier simulation but I haven't purchased that title yet (only the demo) so I haven't tried it.. Though Assetto Corsa is probably a little more polished, probably a little better physics.
I highly recommend giving it a shot.
