Revision: I didn't think this through unfortunately
While mulling over the convoluted continuity and how often the editorial fouls up though admittedly that's just human error at work. I came into a thought would continuity be a lot easier if there was no shared universe? And when I say this mean just plant the characters on separate Earths where they are the only characters that exist and matter there. Superman and anyone related to him can live on Earth S. Batman and anyone related to him can live on Earth B. Wonder Woman and anyone related to her can live on Earth WW. Green Lantern and anyone related to him can live on Earth GL. The Flash and anyone related to him can live on Earth F. Green Arrow and anyone related to him can live on Earth GA. Aquaman and anyone related to him can live on Earth A. And if certain characters who cannot sustain a solo title they can just share a book, like the Charlton characters who aside from Captain Atom have not been able to have successful solo titles can just share a title and live in their own world, Earth CH. Heck if you want to give the Atom a solo book he and anyone related to him can live on Earth TA. Yes this concept is basically the same as DC's Earth M concept and that brings me to the pros and cons of this idea
Pros
-No books will be tied down by what happens in another book because each world is it's own one. i.e. character A died in this book so he or she cannot used until something brings them back to life.
-Continuity will still be convoluted but at the very least other books from other franchises won't be stepping on each others toes because something happened in book A that affects book B. And continuity could be more straight forward.
-Writers will have more freedom to do as they please.
-Crossovers (depending on your perspective) will be more interesting again. I never quite liked the team-up and events because they don't have the level of culture shock and uniqueness that they used to back then and if a crossover happened it would be something special (well to me at least).
-Spin-off titles are still possible even team books.
Cons
- Team books while possible will not be able to add characters from other franchises. Nor can team books revolving around cross franchising like the Teen Titans and Justice League exist (though Earth One Teen Titans is an attempt to try and make the Teen Titans without Dick Grayson).
- Relationships between characters will be like pen pal relationships.
- No inter-franchise pairings.
- Spin-off titles will be confined to the character's designated Earth.
And that's all I have at least for now. So what do you think will such an idea work? Do you hate it? Let your thoughts be known. And if you have more pros and cons say it.
