All your characters must have a profound appreciation for other cultures, their art, etc. (or else said characters are evil). They can have an intellectual discussion about a race's art within three seconds of first seeing a painting, play any musical instrument by watching anyone else do it, and they never
ever find anything not to their taste.
-The only time they find something NOT to their taste, is when it's something that's supposed to be gross, and is made by a barbaric culture. (Live worms, for example.) However, your characters are FAR too polite to ever say that eating *insert gross dish here* disgusts them.
-Characters never run out of arrows. Unless you're going for drama. Then they run out of arrows all the time, and they never figure out "hey, maybe I should bring more arrows next time, since lucky 7 just ain't cutting it for me", despite the fact that your characters are the smartest people EVER. (Except for the comic relief s/he's just an idiot.)
-The only time a sword will break, is if it's the villan's sword, and the villan has just been defeated. Since the villan's evil aura is no longer holding it together, the sword will break into a kajillion pieces.
