Unless I am mistaken, I personally saw this as a somewhat lighthearted parody role-play, a loving deconstruction of genre with some slightly more serious overtones at times. I would most certainly not mind doing a more serious one by any means, however. It is just what I understood when I read the introduction. 

In terms of characters, I was thinking of making a half-serious [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/MysteriousStranger]Mysterious Stranger[/url] for hire. Mysterious unseen guy observing the other characters [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/SinisterSilhouettes]with his face mysteriously hidden in shadows[/url], wearing a [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/BadassLongcoat]mysterious[/url][url=http://tvtropes.org/pmwiki/pmwiki.php/Main/ConspicuousTrenchcoat] trench coat[/url], [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/SinisterShades]mysterious shades[/url] and [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/CoatHatMask]mysterious hat/mask[/url]. He wouldn't really have any actual goals, interfere directly with other characters, or really do anything besides [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/IHaveTheHighGround]standing ominously on lamp posts[/url] whenever anything interesting is happening. Who is he? Who does he work for? Nobody knows. What we do know is that he is [i]Mysterious[/I], with a capital M. Maybe he works for some sort of nebulous [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/TheOmniscientCouncilOfVagueness] Omniscient Council of Vagueness[/url] or [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/EvilInc]Evil Corporation[/url]... Maybe he's just a particularly tenacious ARA agent looking for tax evaders, or maybe he's even just some weird guy who likes to dress up in a trench coat and watch people doing things from rooftops.
Either way, what [I]is[/I] known is that he offers his services to the highest bidder, providing top of the line [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/CrypticConversation]pretentious needlessly ambiguous double talk[/url] and enigmatic cliché statements like "It has begun." or [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/AllAccordingToPlan]"Everything is going according to plan."[/url] to those willing to pay for it... Or does he?
Comes with his own ominous background music and weather effects. Internal monologues not included.

Basically, a character who's sole ability and role in the story is being mysterious and enigmatic.
