3.4 Ownership & Possession
This is the drive where users are motivated because they feel like they own something. When a player feels ownership, she innately wants to make what she owns better and own even more. Besides being the major core drive for wanting to accumulate wealth, this deals with many virtual goods or virtual currencies within systems. Also, if a person spends a lot of time to customize her profile or her avatar, she automatically feels more ownership towards it too. Finally, this is also the core drive that makes collecting stamps or puzzle pieces fun.
