It looks like Valve will also require “parental permission” for users of the Steam platform located in the EU like Riot will with LoL, thereby making EU GDPR a super-COPPA. Users suspected to be under 16 may be locked out or otherwise have restricted functionality after Friday.

It is very likely that these changes have been made due to the impending General Data Protection Regulation(GDPR) laws. These laws will come into force tomorrow, therefore until then all European Union companies, and companies whose consumers reside in the European Union have to be GDPR-compliant or face fines.
Recently, the League of Legends creator Riot Games players under the age of 16 would require parental approval to continue playing League of Legends as of Friday. Riot Games, in a recent announcement, said that according to the GDPR laws the account holder below the age of 16 would need parental permission to continue playing.
Steam and Riot are not the only gaming platforms to be affected by the upcoming GDPR laws. Super Monday Night Combat, Ragnarok Online, and Loadout had to be shut down due to the General Data Protection Requirement.
