Update: I found someone on Discord who unlocked it by happenstance. You have to finish a Grand Prix race with the lowest possible Safe rank provided the number of racers doesn’t drop below it.
So for example, if the Safe rank bottoms out at 40 to qualify for the next race, you must finish in 40th for it to unlock. If there’s 39 racers or less left in the race and you place last (which technically should meet the criteria), it won’t unlock.
I was hoping this wouldn’t be the case, because virtually every race has enough racers KO’ed to drop below the rank. This is so needlessly situational, and I dislike how it encourages sandbagging.
I know everyone wants the Captain Falcon GTA F-Zero, but the whole reason the franchise appeals to me is its purity as a racing game. GX pushed the absolute limits of what arcade racing could be, and there hasn’t really been a non-realistic racing game since that has a skill ceiling that high. It’s absolutely mind-boggling what Amusement Vision created with GX twenty years ago.
Adding vehicle weapons, RPG mechanics, or a GTA like open world would probably garner more sales and interest from average joe gamers, but doing so would lose sight of what makes this franchise great. All that is probably more likely to happen than not should there be a new installment, as much as I hate to admit.
