I have a solution , yet I am new to the game I think in this way = it depends on the gift , make people pay speakers for it like 25 or more , so they need to buy more speakers with crowns that cost money. And their daily speakers will be gone until next day or they could buy more to chat with ppl... I’m just thinking like that , or you can make the gifts cost gold - trillions for each maybe?
Gifting will just be the same as on pimd if it actually gets released. So yeh basically what you said some things will cost nobility and some will cost gold.
