How are each storyline connected is it by time or by universe? (Or are they all taking place at the same time and universe)
Well the biggest “Universe” I have with confirmed stories sharing that common world is the massive“Strangeverse” concept I’m tooling around on that has about 20 separate stories (and one mini-series) assigned to it at the present time. That’s just a world where I’ve essentially jammed 90% of all my supernatural/paranormal/preternatural ideas into.
Runner-up would be my huge “Kashmir” universe that has about 13 stories total (both from the main timeline and a smaller anthology of short works focusing on specific events/characters only mentioned in dialogue/flashbacks in the main books).
Clocking in at 3rd would be the “Cardinal Universe” which is the name for the world I’ve expanded off from my “WEST” story, involving “EAST”, “SOUTH”, and “NORTH”, making for a total of 4.
4th would be my “Live Gear” post-cyberpunk concept that has only 3 stories total in it’s world, so you can see the significant drop off from the size of the top two to nearly everything else…
There are a few other small groupings of 2 that I don’t feel like listing, and usually these are in a cluster of concepts I like to call my “Thesis Stories”. In these I’ve mentally latched onto a philosophical idea or just an aspect of society, and I cover both sides/extremes of it using two different stories to make a case for and against it in each one. These duos normally share a universe by the very nature of their subject matter.
Aside from these, there’s a loose smattering of stand-alone stories that don’t fit with anything else and thus stay on their own. In the far flung future if I got enough of these damn ideas actually made I think it would be fun to do non-canon “What If?” cross-overs.
