They may not qualify as AAA, but Hearthstone, League of Legends: Wild Rift, Kerbal Space Program, Cuphead, Gwent, Genshin Impact, ReCore, Ori 1 and 2, Hollow Knight, Fall Guys, Pillars of Eternity, Call of Duty Mobile, Subnautica, Firewatch, and Valheim are pretty big games; some indie hits but many are produced by major studios.

For one thing, I think the "powered by Unity" branding is a problem, because you only see it on games that couldn't afford to actually pay for Unity and therefore have a larger chance of being poorly polished.

Half of these games run like absolute trash though.

Anecdote: Dyson Sphere Program runs at a buttery smooth 60 fps, and it is written in Unity.

...at least, until you start building the actual Dyson Sphere. ;)
