I trained this model with in-game images from The Sims 4, as well as a few "game-like" images from twitter.

This model works best at 0.8.
This model does not like the "source_anime" tag, so I would recommend not including it. It also has a rough time keeping body proportions. I would recommend using another Lora at a low strength to help combat this issue.
In my examples I used the Sims lora at 0.8 strength with 3D Animation [Pony style] at 0.3 strength.
