Personally, it's the game I've spent the most time with and the one I'm most in tune with the driving mechanics. Many people prefer the previous game Assetto Corsa because it offers mod support, but ACC has both up-to-date content and more up-to-date technologies. Focusing on GT class track races, the game includes GT2, GT3 and GT4 cars. ACC, which has the official license of GT World Challenge, has also added many new tracks and cars with downloadable content packs over the years. ACC is currently the racing simulation with the largest audience outside of iRacing.
