To me, Red Bull Ring, Fuji Speedway and New York could provide the best racing even though I don’t think they have the best layouts. Monaco I would skip like I skip Eaglerock with the kink but for the sake of those who voted for it, I hope it comes to the game.
For me, you’ve got to look at the potentional alternative (or historical) within the existing circuits
Imola - pre Senna’s death
Mexico City - remove baseball stadium
Interlagos - full version - goes around the outside of Curva de Sol
Portimao - up to 32 different options to pick from
You need to go back ~20 years before Senna’s death for Imola to be the real free-flowing circuit it once was, by the time '94 rolled around you had the awkward Acque Minerali chicane and the stupid Bassa complex on to the start-finish line. It’s arguably a better track now (even with Tamburello and Villeneuve nerfed) than in '94.
I’d love to see pre-'90 Interlagos though, for that cauldron-like feel.
Man, just bringing back the 11 on this list that were in previous FM games would be no slouch of a lineup. As with everyone else, I’m crossing my fingers for Interlagos one day, but completing the IMSA schedule and bringing back the missing Japan circuits would make me a happy camper. I was surprised that we didn’t see Sonoma return with NASCAR too.
