I am thinking about doing my first Beards & Beyond hack called The Van Knights of Van Nuys. It takes place in a mythical land called The Valley which is fantasy 80s vibes. Players draw mythical power from their tricked out vans and protect the realm from evil moped driving skeletons.

Vanformers
Van conversions take on a whole new meaning. Not sure what system I would hack for this, but mech battles with vans. 

When I initially saw the jam I wanted to lean into some of the really trippy artwork, thought it would make for a really fun world to explore. However that isn't always how inspiration works, found myself instantly drawn towards those vans with the dark Frazetta style murals on them... 

The Lords of Chaos roar into town to play a show they'll never forget, assuming they'll survive the night. What can go wrong when playing a metal show during Samhain?

Live on stage Final Harvest performs a blood sacrifice to demonstrate how metal they are, the floor erupts and the spires of Hell rise from the depths. Concertgoers are consumed/morphed by demonic forces, becoming a fight for survival as you try to get back to The Behemoth, your '79 Dodge Van Charger. 

Do you flee the scene in an effort to outrun the forces of Hell or do you ascend the Tower to send Samhain home?

Still need to figure out system here.

Oh god I just figured out my concept. 

You have 3 stats: Gas, Grass, and Ass. 

Nobody Rides For Free

Wasteland War Van: travel across the post-apocalyptic wasteland scavenging materials to decorate and repair your van! I'm thinking it'll be a drawing game where you draw the decorations you put on your van, draw and erase where it gets damaged, then draw new art over it.
