I'll be honest, I'm not one for cities. Crowded thoroughfares and bustling nightlife really isn't for me. I'll gladly take the suburbs or even just small-town life out in the styx somewhere. But that doesn't mean that I don't want to visit cities from time to time. There's always plenty to see and do. I just wouldn't want to call one "home." Well, for as much as there is to see and do in someplace like New York or London or Hong Kong, there's even more to see in Sig: The City Between. And that's just the topic of a new sourcebook for the Spark RPG that's up on Kickstarter now.
Sig is a truly multiversal city. Portals from all over the various planes meet there. As such, there's pretty much anything you can think of to be found there. Pick an alien or planar race and you'll find someone there. Need any particular type of exotic good? It's in some market, somewhere. Are you looking for information about a particular quest? I'm sure someone's heard something about it.
The book is up on Kickstarter now. Don't know about the Spark RPG system? There's reward levels that get you the core book as part of your pledge. The campaign is more than 4x funded, but is just in their final day and change. So if you want in, you'd better hurry.
