Project CARS expects you to spend hours on end, placing all your concentration on the race at hand, perfecting each turn, to chastise yourself for making simple mistakes, and to drive the same course over and over again in an effort to get that "perfect lap". While not all of their efforts have translated perfectly, Project CARS comes pretty damn close. Some frame rate drops hampered my experience, but overall Project CARS has done what it set out to do: build a fantastic looking, authentic racing simulator.
You can polish a turd to make it look better, but in the end, it is still just a shiny turd.
It's a fun isometric shooter, if you can forgive the stifling controls. The game doesn't last long, and there's no major incentive for you to go back to replay a level.
