When me and a few others would go clear across Canterlot to this video game store to play some games on the in-store displays, I remember this one filly, way younger than us, that would watch us play Grand Theft Carriage. She even played a few times herself.
She was in advanced classes and made excellent grades. Sorry, I just don’t buy the whole “corrupting youth” thing. Can make ponies more jaded and cynical, maybe. But she never had a problem with it.
By the way, we’d sometimes get paid bits for playing those games by the owners. We’d make them look easy and customers would get drawn in.
