The ability to rent out collectibles such as weapons for a fee then have the item securely without the need of trust transferred back into your wallet.

For example I rent out my super rare weapon for 150 Enjin a month and after the month expires the item is transferred back to the owner.

This would give an incentive for people to invest in blockchain games because they can make their investment back and even more, as well as it is good as the more the item is handed around the more the developer gets their Enjin Fees thus funding more their development, it's a win win for everyone.
