Turn10 keep posting pictures of tracks with a question. This time it was Suzuka, last time it was Road Am. I keep putting ever so polite comments mentioning track ribbons missing from previous games. In these instances both 'West' circuits. Someone else mentioned Bugatti circuit. Last time i managed to shoehorn Sonoma in to my comment (One of my favourite 'i'm useless but i enjoy it' circuits).
I'm sure it's just a bit of PR and that there are better places for me to make suggestions (Forza forums if they still exist?)but i've been having a bit of fun with it anyway.
Edit: The other suggestion was Nords 3x Sprint ribbons from FM4 as a useful learning tool.
