At the risk of possibly sounding crass, the practical solution is to simply never tell them of the decedent's passing.
Unless the matter of concern is a legal or financial one (eg: bank accounts, pensions, insurance, etc.), quite literally nothing and nobody else requires knowledge that the account holder passed away.
Never tell Valve that your gamer dad passed away and they will be none the wiser and noone will have any problems as you "inherit" his account and its associated games. You're not trying to defraud Social Security as a 150 year old, after all (...right?).
