A Spanish track would be nice as we don't have one from that country yet. Valencia's purpose-built Circuit Ricardo Tormo would be the obvious choice as it was in RACE 07 (and in my opinion it's a good track) but Catalunya, Jerez or Motorland Aragon would be great additions.
So I hope the dream comes true one day ---- lol But Francorchamp is a must too, which you haven't on your list at the moment .
Nordschleife already confirmed, but id definitely take Road America, actually tested on that track back in 2004 when I worked there. Kinda picky though, no one besides iRacings laser scanned version has been done right, but seeing how R3E's tracks are currently progressing, I have no doubt in there ability to create it or any other track.
Errr What he said... Spa is also confirmed. Suggest you maybe read through the whole of the thread, I'd make a coffee first, this thread is getting rather big these days lol.
Yeah, I had heard that they were working on Nords, I was just commenting on two tracks at the top of my list. R3E has an excellent track list as-is but you can never have too many.

For the American side of things: Watkins Glen, Long Beach, and Road America For everywhere else: Interlagos, Imola, and some of those wonderful tracks from the STCC expansions
Here's my take: V.I.R. (with all layouts, because Virginia Grand West is a hell of a track, even more a US Green Hell than "regular" Virginia) Road Atlanta Brno Imola Spa... ...and many more!
TL: DR, but Brands (GP) would be good too, probably easier than starting from scratch as you already have part of it?
have had 3 boats of fun at circuit de Pau in race 07 driving f3000 and wtcc would love to see it in raceroom
how about some real hill climb tracks. Pikes Peak for example - it`s all tarmac nowadays. In Austria we have the Rechberg Race, Grossglockner would be an option as well, or ever thought about racing the Stilfser Joch with a racecar?
