I really enjoyed games like Red Dead Redemption 2 and CyberPunk 2077. They are not per-se reality as in as you and I live today, but different lifestyles in different times.

I feel like these types of games really benefit of the work that is put in to making humans and environments look realistic.

Heck, even if you're making some weird alien world you're still going benefit from realistic physics engines for example, because that's just how our universe works.
