Should "Titles in different regions" (at very least English speaking ones like US and UK titles.) be added under When To Create a Redirect?

Not a bad idea. Syndication titles, too. Got a good example in mind?
Dragon Quest/Dragon Warrior would be the example I use, but for some reason Dragon Warrior is currently a Disambiguation page for the main series and a single spinoff work (this could easily be changed though).
Failing that, Girls Mode/Style Savvy/Style Boutique is the first I can think of
Mm. Usable, but the full names are a very large. I found a good example that doesn't require me to type as much <grin>: the British series Spooks, called MI-5 in the U.S.
That one seems like it would work.
