Hi Txema.
You could find rFactor and rFactor 2 on Steam.

We use Rfactor 2 in this community, with two new championships starting soon. You would be more than welcome if you fancy a race. I'd like to invite you to visit to the presentation page and tell us more about you. http://www.rfactor-sp.es/foros/forum...-y-Bienvenidas
