rfactor is a race "sim" done some years ago by isi team.
rFactor | The Future of Race Simulation
the game is quite cheap (about 30 dollars online buy if I am not wrong),cause the developers didnt make the original game with real cars (and royalties), but they want to provide mostly a base for all the add ons mods done during those years (all completeley free..is incredible the work done all around the world with so much passion by enthusiast fans,without earning 1 euro.).
Rfactor central comunity :
rFactor Central - Community Driven Race Sim Resource for rFactor by ISI // Car mods, Track mods, Car Setups, Screenshots made and is preparing a lot of nice add ons for it, u shall test theme everytime,cause being all free stuff u will found nice and quite simulative ones and also very easy or nut mods (try have a look at stinker mod..u race with giant 4 wheel WC

).
Nowadays the mod offer is very large,and u can enjoy open wheel series or touring cars, also from the past (downloading now the new mod for BMW E21 v.2.0),and everytime u will found people online gaming somewhere,also cause it is very easy to get involved in a local league (I was in aussie v8s, and was a cool opportunity to learn wonderful tracks as mount panorama,stricktly in my Ford Falcon...).
Also time by time they add new tracks...they only cant give any secure release date for mods cause is all done in other people free time.
Any modern pc runs well with rfactor,a decent video card allows u to play at least at a lower resolution but with a good frame rate
If u have a modern video card (new geforces) the game comes incredibly nice and full of special effects,but always lower if compared to the graphic details of Forza in X-box, thats dedicated hardware and always runs faster.
IMHO the real difference between Forza or rfactor is that nearly every week u can have something new to test (and to race online).Again, depending from the difficult u like, u can choose really a lot of different locations and ages..(and dont do as I do, always in Nurburg..)
Very often I use to host a night server for Nordschleife without any driving aids (neither clouch)and full damage options...and also if sometimes is frustrating,its easy to find guys (mostly british or germans)racing incredibly good there...with the cool sensation to destroy all at the last turn...
