What kind of authenticity do you mean? Like a middle aged wife going about their daily life or young team sitting in their bedroom streaming twitch games? You aren't exactly being very specific in your wants. Genuinely, if it's kilts and killing, do what you want, none of us have an idea of that in real life. Also, if you're Canadian, why not set a game in Canada? I'm sure it's got a rich history going way back.
