Actually, there IS a modern sprint car game out right now. iRacing. It's not really a game though since it drives more like a simulator. It's also different than the other driving games because you don't buy the game, you subscribe to the service instead. iRacing has a non-wing pavement sprint car series that enables you to race against other real people online (no "artificial" cars). All of the tracks are real, and the car adjustments are far more realistic than the Ratbag game from 10 years ago. The realism is FAR superior to any other racing game I have played. iRacing also has the Silver Crown car, but it's the silly Hoover vacuum model from a few years ago. If you haven't checked out iRacing, go take a peek.
