The most important thing for people, and by people I mean all of us at times, is in-group belonging. None of us are immune to that. We look to our peers for cues on how to behave and what to believe.
Some people consider like scientists and experts in-group, and trust them. Some don’t.
This need for in-group cohesion is more important than facts and figures. It’s more important than the text of some book.
So when all your friends and family are saying that Christianity means one thing, it’s unlikely you’re going to disagree.
Probably any game with a story. Voiced might be better, but written has advantages, too.
Might not want games with a lot of fictional words or idiosyncrasies. Like Baldur’s Gate 3 is really good and well acted, but you’d pick up a lot of less useful fantasy words.
Just looking at what I’ve played lately.
Guild Wars 2 is a great game. Lots of content. Most of it voiced. There’s also other players you can talk to, and some might speak your native language. It has some fantasy jargon.
Grand Theft Auto 5 would probably teach you swear words and other stuff you shouldn’t casually say. Be careful with that one.
My time at Sandrock was fun. That probably would give you some vocabulary.
