New player, an idea from a different ecosystem.
Perhaps introducing a system that allows player to earn future royalties from all futures sales of the items (unless they are burnt). E.g. 1% royalty
Whether this is from crafting a unique rare item, a rare skin or fusing 2 illivums to make a highly powerful illivums (after grinding to breed and evolve it).
This doesn't need to apply to all items.
This should make the game more fun and get more people into crafting/fusion and involved in the different aspect of the game while keeping them hooked in the game longer.
Update:
the royalty stays permanently (to the original wallet) and doesn't change after trades to a different wallet user.
