What features do people want to see in the FM franchise apart from those mentioned in the OP?
Personally I want to see the loading times addressed, more diversity in types of races, a championship mode, all cars unlocked in free race, rivals reworked so it worked more like the FM4 network test, bring back maple valley and fujimi kaido, less popular real world tracks like donington and oulton park, accurate in car audio (give the option to switch for people that like it loud), from the beginning of the game don't have things like the racing line active with simulation steering as standard activated, expanded customisation, wheel-less view and helmet view.
Adjustable race lenght in carrier, better pit stops and at least some flag rules
I would also like to see better replays. Something that is focused on a race and not on just one car. Maybe new preset called TV or something. Now camera cuts way too fast.
