"I'm running 3 campaigns and always forgot what happened last week. This actually saves me so much prep time because I can just read the summary instead of going through my terrible notes"

FAQ

Does it support 7th Edition rules?

Yes. It understands concepts like pushed rolls, luck spending, and the modern sanity mechanics of 7e.

Does it work for Delta Green?

Yes. The system naturally adapts to modern settings and conspiracy-style investigations perfectly.

Does it track handouts?

If you read a handout aloud or discuss its contents, Saga20 will index it and associate the relevant clues with your investigation summary.

What about Pulp Cthulhu?

It handles the higher action and pulp talents just as well as the purist psychological horror style.
