The Game API have been updated so you can now list assets in the order that best suit your game using the /game/v1/assets/list endpoint.
There are two new query parameters that can be sent.
order_by which is the field you want to use for ordering your assets. Valid options are name, created_at, updated_at, and id.
order_direction is the direction you want to order your assets. Valid options are ASC and DESC.
