I think the only thing that sticks out from when I played through this game's Championship modes is, besides finding out by accident about holding down to steer sharper [plus a few other strats I looked up], that there are NO Credits for beating the Reverse Championship, the last one you can get and unlock from beating the Expert one [and the ones before that]. It is quite weird that it has no credits sequence at all as an extra reward or even an acknowledgement for clearing Reverse Championship [besides your records], even for an early N64 title [MK64 had a credits sequence].
That aside, it was a blast to play through that game and finally go beyond the Hard Championship, as I went for it thanks to the RetroAchievements set allowing me to keep those completions tracked. Getting a perfect record over Hard still eludes me though, but something that I may achieve one day if I can survive Twilight City in first one day.
To be added - go check out the soundtrack though.
