How come the Mario Bros. don't marry their respective princesses?

I get that the Mario games (and Luigi games) and the characters are designed to appeal to gaming fans of ALL AGES, but how come Mario and Luigi don't marry Princess Peach and Princess Daisy, respectively? What kind of message is Nintendo giving to KIDS who are into their games? I've kind of wondered this... show more I get that the Mario games (and Luigi games) and the characters are designed to appeal to gaming fans of ALL AGES, but how come Mario and Luigi don't marry Princess Peach and Princess Daisy, respectively?

I've kind of wondered this for years.

I think Nintendo would give out a much better and more positive message to youngsters about relationships if Mario and Luigi OFFICIALLY married their respective princesses.

I am just curious about this. Please help- thank you.
