At the risk of being morbid. My mind went on a tangent and i began to wonder what happens with digital purchases once you die. Do they just linger until the account has become inactive long enough and then it's just deleted? Do any of these services even count as assets? What if you had currency in an account that had not been spent? Is the service responsible for making sure those funds are even owned by a living person?
The games themselves are not assets since what you own is really a 'single user licence' to play, so you own nothing there. The funds in your wallet could be seen as an asset, but unless you have $500 in there they are probably not worth pursuing. You could call Customer Service, but in the end you might need a lawyer or you might need to spend hours on the phone, so it would cost more than what is in the wallet.
Thats the thing though as more things go digital it makes only sense that you could "pass along" that licence to another living person. I'm sure as time progresses the legality and laws surrounding digital purchases and lockers will start to become more clear. Its an interesting topic though.
