the only problem I see with this is that very few people actually have unique avatars or ships, STO doesn't have the kind of customization Spore has.
I don't consider this much of a problem. WoW has less customisation and it has figureprints like Spore's, all they really are is armour showcases. It's more about the attachement to your character rather than whether they look like someone elses. It may not be unique, bit it IS yours.
