I've always wanted to write...

What's a story you've always wanted to write, and just haven't gotten to yet? Is the idea not fully formed, is it the subject matter your working on? Why aren't you writing it right now?

Original works, but namely one that delves into many a character in their own world stories all playing a bigger part in one showdown between 3 groups.

Another one is more or less a traveling in a dystopia, ruined medevial fantasy world (mindset like dark souls but different lore and stuff) dealing with three peeps trying to find hope and purpose as they merely exist.

There's one Pokemon idea I have where a couple characters from X/Y go to the Pokemon World Tournament in Unova, and they end up being dragged in an attempted assassination attempt. Two big problems being faced are how one character is able to get away from police, and why an assassination attempt on them. Foul Play then happened and I didn't get a chance to flesh the story out further lol.

I then thought about an original story that's like Faust meets the 1940s. One reason I haven't gotten to flesh out the story is I feel this would fit more as a webcomic due to its supernatural elements. Another reason is there's this show called Lucifer that seems like it'll have similar themes to my story and I haven't gotten the chance to binge watch the show to properly assess it.
