A comprehensive topic you could talk about are what responsibility the developers and companies have to ensuring privacy and security in their games. In the modern world, everything seems to be connected to some account, and needs permissions on your phone. Developers have some sort of responsibility in keeping their games secure, but also have some sort of responsibility for what they themselves can do with the data they collect.

As far as social issues, you can discuss the extent to which politics are injected into a game.
There was that stuff a few years ago with SJWs in games or something (I personally didn't pay too much attention).
There was the one level in Call of Duty where you were forced to kill civilians, see:

Maybe go off something based on that, what is acceptable for a game to show?
Maybe could go into psychological effects, like pay-to-win addictive "gambling" in games, or positive effects from "therapy" games.
But you also don't want to go too out of scope, better to focus on a few things in depth than sprinkle the paper with a bunch of disconnected issues.
