I looked at your link.
Thanked in 1994. Warcraft's developement started in 1993

He was born in November 1990. That means he was 2 when Warcraft: Orcs and Humans started. 3 When it came out.
So what you're telling me is someone got his son's names into the "Thanks" when they were respectively 4 and 2. Then continued to give them "Credit" in games to build their credibility despite the fact that, not just by law, but by Professional Ethical Competence could not execute the duties "assigned to them in the credits" thus creating a CV under false pretense. So, this would be considered Professional Misrepresentation on the part of those including this on their resumes and fraud. It's also perjury. Not to mention "
Stolen Valor" for the dozens of uncredited Entry Level Developers, Interns, and Independent Contractors that never got their names in the credits for contributions for the properties. You can't blame the kids for the stolen valor as that onus would be on the parent who started putting their names in the Credits. However, after age 18 - it's would probably serve them to issue corrections to Moby Games, Wikipedia, and IMDB under "Family Attribution/Support" and not whateverthefuck I just read was.
I guess that would mean their daddy, Joeyray Hall, basically set them up with these "Credits" despite them being diaper-babies that shit themselves. Fraud is just in the family and they wallow in shit.
