I really wonder what's going to happen if Blizzard (aka hearthstone) or someone else big (Steam) get shot with the GDPR bullet 1st.
GDPR has special and more stringent provision when dealing with Minors data.
Everybody look at the adtech industry as the one with the highest risk regarding GDPR but the Gaming industry (especially for online and mobile) is the one that can be shot first because of the Children's provisions of the regulation.
This won't be pretty. Backend engineering efforts to address this only began a few weeks ago, given unclear "technicalities" that had to be addressed in interpreting the meaning of "right to be forgotten". I'm guessing other companies are facing similar issues, especially if any part of their user data collection pipeline is backed by the "cloud", and these access points are heavily throttled in terms of read/write requests.<p>You would think that migration efforts would've happened sooner, but alas, like global warming, it's one where it seemed like "waiting until the last minute" was a preferred approach to "invest $$ in this now and use up engineering resources on something that we really don't want to do because it hurts our bottom line".
