She doesn't even have the same name but I'm very very fond of this character and the world that I created around her. Every once in a while I go back to her and attempt to create a story around her. I love everything about her but I think, in the end, no story I ever give her will ever be good enough and... I think she's just one of those private characters of mine that I will never end up publishing.
Anyways, I think fanfiction is a WONDERFUL thing and it's a great starting place for any writer. You don't have to worry about character or world creation. You just focus on 'story' and it even makes you feel comfortable. Hopefully it will lead you into bigger and better things, but go at your own pace for that. If you never write anything else, that's fine, too.
As for taking pictures from the games, shouldn't be a problem as long as you aren't trying to distribute your game en-masse to the public afterwards. If it's just for your enjoyment and maybe handing it off to one or two friends to read your work, I'm sure the creators couldn't care less.
