A respectable racing simulation game created by the company Kunos Simulazioni, released on December 19th of the year 2014.
The game has 178 different vehicles to choose from (a good chunk of them are paid DLC) and it is possible to mod
the game to add more, though a lot of mods are of poor quality from personal experience.
The game has 19 reasonably detailed tracks with no default rainy or snowy weather conditions or day/night cycle, so one may prefer another simulation for this reason. Again, it is possible to mod the game to add more tracks.
As for realism, Assetto Corsa is reasonably accurate; most of the people that pick on it for ridiculous understeer have no idea what they're doing and can't enter a corner to save their god damn life (or
don't know how to set up their car correctly.
Like, seriously guys; default setups in any game usually favor understeer. This is common knowledge. Change your setup if you want more oversteer, damnit!). The game also has quite good graphics for its time, and you should be
fine running it on medium to
high settings with an
RX 560 or better. The sound design is tolerable, perhaps a little mediocre.
Me, to a friend: Hey, have you heard of this
game called Assetto Corsa? You might like it, I know you're into
sim-racing.
Friend: Oh, thanks! I've heard of it but
never tried it. I think I'll install it today.
