Nuka World(s)

I have something of a hobby within a hobby: not just making and playing RPGs, but specifically, making and remaking hacks to play my favorite video games with friends. I’ve already made two hacks to play Fallout, and have been kicking around ideas for a third, built on the system for Exhumed. I really have to finish designing that game before I can hack it to do other things, though, so I figured I’d blog about my previous Fallout hacks to hopefully get it out of my system for a while.

WORLD OF VAULT-TEC is a hack of World of Dungeons, requiring only a couple six-sided dice to play. It worked fine when I ran it before, but if I were to do it again today, I’d probably scrap the weird crit system and possibly skills as a whole. World of Dungeons: Turbo (Breakers) would probably make a better base overall—you could just replace the talents with some extra, familiar perks, and the stats with the SPECIAL stats, and be good to go.

VAULT 20 is arguably a hack of Knave I made before I was aware of Knave—stats range 1–10 and are added to your d20 roll to test for success, usually shooting for a 16 or higher. Unlike Knave, though, most stats started pretty high (5 was average), which felt pretty unwieldy to me at the table. The players didn’t seem to mind, though, and generally agreed with my wife’s advice that adding a number to a roll is always more fun than subtracting a number from a roll, so I’m taking that lesson to heart.

Both games have some random tables for items, locations, and creatures that could be handy if you ever run your own Fallout TTRPG, regardless of system. I posted a few more to G+ that didn’t end up fitting anywhere else; maybe if I ever get around to another hack, these will go in there. For now, I present them below in advance of G+’s imminent closure.

If you’re looking for more lightweight hacks to run Fallout, you might want to check out World of Mutants (another World of Dungeons hack), and Death is the New Pink (a hack of Into the Odd that I believe existed in an earlier form as a straight-up Fallout adaptation). And if you have a favorite game you use to run Fallout yourself, please feel free to let me know in the comments!
