Possibly integrate a trading system where players can trade things like cosmetic tokens or cosmetics in general to the island? For example I have a cosmetic my friend has been trying to get and I already have. I got an extra blueprint for the cosmetic but due to owning it I can't claim it. Instead of selling it for knick knax tickets or giving it to the king, I could give it to him for x amount of gold or another cosmetic. People I've mentioned this too think that there could be a chance of people scamming others so I would just strongly suggest to those people to only trade with their friends that they know they can trust.
