I would give it 5 star but a lot of online players ruin the game. No matter how well you do in qualifying, come race time you're always rammed off the track. I get into top 3 a lot, but end up near the back after first corner cos get rammed off. An update for harsh penalties is needed. It's that bad that there is a clean racers league on the official project cars forum and this is organised everyday. Single player is ok but it's mostly online where action is at, or should be. Would be better if they could sort this out.
