BGG Thread: User Review: "If players add in such factors as two car teams, full race seasons, high wing/low wing settings and advanced rules with pit stops, Formula De becomes the best road racing simulation on the market. We ran a race one night with 12 players on the Monaco track using advanced rules and the weather was rain the whole way. The tension and grim set of faces around the table was awesome. Normally a game session such as that, with all 12 players knowing the rules would have run maybe 2 to 2 1/2 hours, but this one ran well over 3 hours and when done the faces of the players were similar to ones I recall from my youth as a motorcycle road racer on the West Coast: elation, weariness, awe and a knowing smile.
Any board game that can create that is worth the price. In fact, I own every track expansion and all the metal cars along with a couple of sets of aftermarket cars I found on eBay. "
