That's a great question! The ashcan is an extremely trimmed down, boots-on-ground field guide for folks to hop into GODKILLER right away and so won't have much in the way of worldbuilding, setting creation, and god generation aside from giving you the fundamental tools to build your own.
My hope is to use the sales from this ashcan run to fund a Kickstarter for a full game where there will be a fuller worldbuilding guide along with fleshed out settings, adventure modules, a more in-depth god-building toolbox, and more! When the ashcan is out, I will gladly welcome suggestions for what folks like yourself would like to see in the full game.
