The only thing I’d ever want analyzed in gaming is the messages that developers convey. And, there should be no “overbearing head agency” be it the government or publisher, that controls that message. Take it just as a suggestion between artists:

We should encourage good morals and themes in the messages our games convey. I know it’s typical for gamers to say they don’t care about story or premise in games, but even if one isn’t laden with cutscenes, they often communicate a concept even just with level and character design, providing objectives like rescuing hostages, collecting loot, or getting stronger.

I don’t necessarily think violence, on its own, makes a message. Showing scenes of World War 2 can convey a lot of things. It can tell you that war is horrible, or it can erroneously tell you it’s fun. I think if you’re expecting maturity from your audience, you can acknowledge that while the game is fun, it’s not trying to foster that feeling in players.

The main thing that leads to violence in the real world is anger. Media can teach us violence is a form of communication, a tool, but anyone using it has a message, one rooted in a lot of hatred. I might even argue there’s some cases where that anger is both deserved and needed, but potentially misdirected; and other cases where both the anger and the action - violence - is 100% needed. A Ukrainian soldier fighting Russian invaders that are trying to kill innocent people does not need to be taught that “violence is bad”.
