I'm not sure how reading novels and being a mentor exactly classifies you as an expert ... and [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/WishFulfillment]Wish Fulfillment[/url] isn't a bad thing so long as it improves and compels a good story. Before I go further, don't worry about me being one of "the people clamoring to get into your good books here just because they are desperate to be accepted." Besides the fact that I feel it's extremely rude to make judgements like that on people you don't even know on a public forum, my character has already been accepted ... so let's move on.

I theorize the only issue you really have with the character is the amount of power this character has. He's overpowered as hell, can do pretty much anything, and is alike to a deity (though he isn't as far as a know, but might be). I can't really agree that any part of his background is done in bad writing because it's quite a unique twist in my mind to take a tyrant able to rule a whole world would've been humbled by his opponents so much as to stop using that power right out, despite how much he can truly change the world. Of course any good story, there should never really be any one character that can snap their fingers and blow the world up ... whether this is because lacking that power or by choice.

Now my real question is, what is the difference between him playing [i]this[/i] character and playing a deity as an NPC? ... he controls all outside elements, after all, except the ones he let's us control. That's how it is in every single role-play. So ... how is this different? Just because his focus might be on his story specifically? Because he's proclaimed him as a "PC?" Why would that matter? It's like throwing a fit when the GM brings in the God of Death as the main villain. Um ... unless it's abused, what's so wrong with that?

You can yell and cry "Mary Sue" all you want, but unless you cater specifically to a world where no greater powers exist, there will always be an NPC/PC that is far more powerful than any character you've just crafted. He could make you feel better by labeling him as an NPC, but that wouldn't really change [u][i]anything[/i][/u], so I'm not sure what the fuss is about - unless you're admitting to judging his ability to role-play maturely before the role-play even starts?

[b]Edit:[/b] Yes, being cautious can be easily justified by this because a terrible GM with this type of character - NPC [u]OR[/u] PC - could ruin the entire thing before it starts. However doesn't the amount of information, story, and uniqueness of the setting not speak for the potential of his setting and characters? I see no reason [u]not[/u] to give him a chance. *Shrug*
