I'd like to know in how far fan fiction writers consider themselves talented. That's why I'd like to know from you: If someone offered you $1000 to write a fan fiction story about a specific "Street Fighter"-related plot (like Ryu and Ken's training years or whatever) that's at least 30000 words long, would you do it?
For this question please ignore the idea that the guy who offers you the money might not be sincere or anything like that. Imagine it's some bored millionaire who's a huge fan of the game, but has zero talent to do any writing by himself, except for giving you some rules that your story has to keep. And that this guy is perfectly willing to pay you $1000 if you could write him a decent novel with 30000 words or more. Also, since it's just for his own personal enjoyment and not for commercially publishing it, forget all the copyright stuff.
Would you consider yourself capable to do this? Would you think you could write such a text that sounds like a real book and not just a mere elementary school project? And if yes, would you be willing to actually really do it?
