I could see Den-O being a hard sell...
I mean, Americans don't like trains...probably why I bet ToQ will get skipped over.
Plus, I mean, what do you think most Western parents will think when they see a red-horned demon possessing someone?
1. Where in the world did you get the idea that Americans don't like trains? If there's one place in the world.....
2. The premise behind Den-O would be excellent. Simply change the design of Momo to be less devil-like and you got perfection.
