Obviously not happy to hear about anyone being stabbed but if I had to choose...
Been halfassing Yakuza 3. Really I probably could have plowed through already but ehhh
The caveat there is that at the time there wasn't a invite system. You'd just add mods. So him getting modded there isn't as big a deal as one would think.
The fact that it wasn't banned until after he was long gone and only then after a CNN piece on it, that should raise an eyebrow.
Might take a look at Temtem and Cassette Beasts to get that Pokemon fix.
The Creeper World series, or Kingdom Rush for tower defense a la Bloons... possibly Mindustry or Factorio as well. Start with Mindustry and if it does it for her then you can grab Factorio as well.
She might also vibe with roguelikes considering she liked Vampire Survivors so Enter the Gungeon, Binding of Isaac, Realm of the Mad God, Slay the Spire, or 20xx/30xx might be up her alley as well.
I was on The Perfect Tower 2 for a while until my 8th ascension introduced a different grind and I lost interest.
I've been on Farmers Against Poatatoes Idle and its mindless enough that I can more or less passively play with just one daily check in.
