Credit. When people work on something, it's only right to expect those people get credit. Unfortunately, the videogame industry is a wasteland of sleaze, and companies seem to think credit is optional.
XSEED caused a fuss last year by claiming it was policy not to credit workers who have left the company, even if their work is part of the game. While the studio's tone deaf nonsense turned heads, it's far from the only company that doesn't give proper acknowledgement.
Withholding credit is another example of how the game industry mistreats people simply because it can get away with it. It's unfair leverage to make an unrepresented workforce compliant. Crediting standards need to be enforced, because non-negotiable enforcement is all the game industry seems to respect.
