THE 10 COMMANDMENTS OF BEING A MAIN MALE LEAD
Thou MUST be a prince of a powerful nation, preferably with a very powerful father that can own you with a flick of his wrist (until thou hast arena abused) and/or a hot momma. Or at least a badass sibling.
Thou must have many different spouse possibilities; in some cases, when girls are in short supply, thou may look towards thine own sister. (Ephraim, I'm talking to you)
Thine class MUST be Lord. Duh.
Thou shalt be a total wuss if thou useth a sword and thine only weapon is a flimsy little toothpick called a "Rapier".
Thou wilt obtain a legendary weapon so powerful, with a name so ridiculous, a history that even politicians couldn't even fathom, and an anime flash so cool before thy beginst thine attack animation.
Thou shalt weaken with age and beard growth if thou were a badass in the previous battle against evil, and even thine fragile mage daughter can own thee with a flick of HER wrist. (Hi thar Hector)
Thou shalt have a pimp of a son who will own thine 50 kg sword with HIS 50 kg sword, simply because his is on fire.
Thou shalt lose thine virginity at the end of the game no matter how sucky thou art for the sake of the plot. There are no exceptions. (Hello Ephraim and Eirika)
Thou shalt 'grow' a horse from out of nowhere when thou promotes.
Thou will go emo on thine dragon girlfriend with thine 50 kg sword because thou art badass with it. There is still hope that she will still like thee when she comes back to life, but better not put too much of that into sex for rejection is a terrible thing.
