Honestly I was gonna go for the Platinum
Until I realized there's 48 BALAN BOUTS!
Balan Bouts are QTEs challenges and if you miss even one perfect you have to let it play out, leave level, reenter level, go to challenge again and retry.
You can not exit them and you cannot retry them.
By far the worst part of the game. They add absolutely nothing.
Edit: the awful sports mini games apparently have statues... (I couldn't perfect any of them)
