Just curious, but is there one that you have more of a story for than the other?

I had PM'd Half two separate concepts and based on our discussion, I'd originally thought that I'd be applying for the [i]other[/i] idea (I still might). But when I actually sat down and thought about it, the only thing going for that concept was that I'd be guaranteed hooks for writing with other people. I had a story arc, but it was really a one-shot and nothing else planned from there.

By contrast, for Arthur, even though I was actually less hyped for it, I had a branching story concept that could keep spinning out as I needed. Which is why I ultimately went with Arthur.

So that's why I ask, are these two genuinely 50/50 for you? Or is there one you have more of a story for than the other?

I'm going to second what Bounce said here.

Also, which idea would you have more fun playing out?

As I see it, the turtles would make it so you are very close to where everyone else is and so make it more easy to integrate into other's stories. While Genosha/Magneto would give you a larger sphere of influence on the story and world that no one else has covered yet.
