On the topic of posting length, nothing amuses me more to see someone who implements such a rule:

[quote][i]...at least 4-5 paragraphs, [b]each paragraph containing at least 10 sentences[/b].[/i][/quote]

And then I start seeing people stringing all the characters' dialogues together into one huge wall of text dump in order to meet that requirement.

[quote=@Tancuras]Man, am I sick of Gary Stus and Mary Sues. So many edgy teenagers who also happen to be "master archers" or "master swordsmen" or "master martial artists" and they're all "wise beyond their years" and they're good at everything and everything goes right for them and there are no consequences for their actions and they have no flaws or if they do they really don't matter anyway. Clusters of cliche and self-insert fantasies.

I miss originality.[/quote]
I don't have a prob with borderline Mary Sues/Gary Stus - as long as they will be subjected to deconstruction (and a dose of [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/MindRape]mind rape[/url]) to beat some sense into them that no one is perfect.

However, if anyone tries to present a flawless God Sue into my roleplay, [i]you're asking me to educate you why God Sues shouldn't exist[/i].
