All you gotta do is pick a track for us to race on, the contestants choose a vehicle, and when the race starts, you'll commentate what's gonna happen next. (EX: "There's a corner coming up. What will you do?" "There are oil slicks on the road. What will you do?" etc.) Then we choose what we're gonna do next and then you spin a wheel to decide if our action is "Super Successful", "Successful", "Failed", or "Super Failed".
Then tell us the effect of our actions. (EX: "(Insert username here) tried to take the corner, but he crashed!", "(Insert username here) successfully avoids the oil slicks!" etc.)
Then, based on that, say who's currently in the lead.
