You’re confusing PEGI (the European games rating body) with ESRB (the American equivalent).
PEGI has ratings 3, 7, 12, 16, and 18, and it gave Balatro the highest rating of 18.
ESRB has ratings E, E10+, T, M, and A, and it gave Balatro the relatively low E10+ rating.
It’s usually because of cheap electrolytic capacitors. Letting a $10+ item die because they were too cheap to pay $0.25 instead of $0.15 for a properly rated component.
