yep yep, the main series is intended for pretty much all ages! there's little to no swearing (a character might say "damn" at some point? that's the only instance i can think of), no explicit nudity, very few instances of suggestive dialogue (you'd have to go out of your way to find it and kids would probably not understand anyway), and of course no on-screen character death or over-the-top violence. there's one battle in the second game but there's no blood and you can choose not to fight. i think that's all as far as possible concerns go?
thank you for asking, i hope she enjoys them if she can play!!
