im pretty sure sweetie belle (raritys sister) is around 8-10 before she gets her cutie mark, and like 13-15 when she gets it, if this game follows magical pony lore tho (i forgor what its called but its mostly known by the fandom, and in it ponys have a life span of around 400 years, the princesses are around 10 thousand years old, and your cnsidered a adult at around 60, making the main six all around 50-60 and the cmc around 20-30) if it follows that its fine, if not.... EWWWWWWWWW CALL THE FEDS AND REPORT THIS GAME or just add a au tag and make this game follow your au where the cmc are legally adults, btw not everyone is freaking out cuz its kinda what we all think sombra would do
