Have you thought of adding a prefab effect like "assets/prefabs/misc/easter/painted eggs/effects/gold_open.prefab" whenever a player receives a gift? Just to add to the surprise factor and spice it up a little with some noise and a few sparkles.
Option for effect when receiving giftSuggestion
Oh! And an optional <reason> for gifting would be cool too!
"Gifted": "You have received a randomly wrapped gift from <admin> for <reason>. Enjoy!"
Hmm okay good ideas
