Even if you were immature, there would still be no reason for you to participate. Please go make more crochet or something and quit wasting your time pointing out how obviously boring my quest for lulz is.
Upon testing my own character using the Universal Mary Sue litmus test, among other tests, I can say that I now have fuel for a new complaint. (Hint: My characters all scored very, very low, for reasons concerning their... well, humanity)
Actually, my complaint has more to do with how the damned tests are completely geared toward human-like characters (including anthros), when most of my characters are thoroughly non-human (physiologically and psychologically). Not to mention that the tests ask so many questions concerning the character's social interactions, when several of said social interactions do not exist in my characters' universe (or at least they don't work the exact same way as they do with humans). That's why the characters scored so inhumanly low; because most of those traits logically could not apply to them.
But yeah, character development is key. Mary Sues are annoying.
I've had the funniest RPs with people who thought there was absolutely nothing wrong with their characters, though. >*Shoots my character in a neighborhood full of people* >*Escapes on a random helicopter before the cops get there*
Alright, they're good for the entertainment factor. I'll give them that! They're always like that too. My characters are freaking androids and I don't make them that ridiculous! People like that remind me of kids who cheat during games. Like when one kid goes "I shot you!" and the other just says "Nuh-uh! I had a bullet proof vest on the whole time!"
