I tried them all. I love lots of them. I simrace sine Indy 500 / REVS.

Yes, you might need to look differently on the product computer games and the way they are priced.
Yes, you might take some time to get used to the different approach they have in terms of ranking, save driving and competition

Take a look. Give it a try and stay a while giving the thing a chance to get used to and to develop a maybe different mindset as well (talking about "different approach" )
No, you might never leave it again.
