I think there should be different challenges in all RRO to unlock clothing and skins to weapons, like:
"Win 50 paintball games as level 50 to unlock..." like a hat or a paintball skin that's gonna be hard to unlock.
"Kill 1000 enemies with a bow in Golden trophy to unlock..." a special bow skin or:
Kill 1000 enemies with a sword in Golden trophy to unlock..." a fancy sword.
I really think this option would make rec room funnier. I'm not saying the game is not funny but I think it will add some funny grind sessions to earn a really fancy skin that you really want.
