Was having a little look around the track list today and thought it would be fun to see how each major real World Series is represented in the games tracks. Just as a bit of fun. The results were surprising for me as I expected there to be less for almost all the series' I looked at, so heres my findings anyway.

As you can see, based on the current FIA World RallyX schedule, only the rallycross series has less than 5 "official" locations (obviously with more RX tracks in game I'm sure the calendar in game will be beefy.). It will be interesting to see the calendars for these respective series in the career mode (if some of them are even represented of course) and how realistic they will feel.
