The hero is an adopted child of a single woman. The hero is born of a virgin. Please, give the hero a dad for once. If the hero does have a mother, then she is definitely a housewife who is cooking the whole time. Your parents can have blonde hair but you will end up as a green-haired punk.
Lovers never kiss, all they do is look at each other.
When enemies kiss you, all they do is blow a kiss, yet you always seem to be charmed. Weddings never last. You never get to play as the baddie, whose HP is always 100 times as much as the hero's. A princess always wears a pink dress and uses healing magic. Oh, and there's always an old man with a beard in there who's really good at magic.
