Does the Universal Horizons title have some sort of meaning in the system, or is it just something to sound cool?
Yes. "How can we denote that this is a generic system in the most bland and generic way we can think of?"
Seriously. The whole premise is taking your one character that was created in one genre and converting it (through their patent-pending method, though their patent was denied like five years ago) to other genres.
That method? "Get rid of racial features when going to a genre that doesn't have them. Magic skills don't exist in modern or future genres, unless they do. Shooting works equally well for guns or bows. Going through Genre Portals magically fucks up your brain so a high level of Sciencey Build Shit skill either results in fancy architecture or literal rocket ships depending on what's genre-appropriate." It's very "just write shit down; we're for damn sure not going to actually make a real conversion system because that's hard."
And this isn't me misusing genre. This is how they use the word. I don't even want to ask what genre something like Shadowrun would be.
