100 Homebrew Adventure Ideas for Starfinder

Game Master Patrick here, and I don’t know about you, but my mind has been writing adventure ideas non-stop since the Starfinder Core Rule Book came out in August. Since we are playing Dead Suns and not running homebrew adventures, I won’t be able to use half of them. But I don’t want them to go to waste, so I figured that I would give them to everyone online for free.

If you’re a GM like me and want to prep and run a fun and fast introductory adventure for your friends, roll a d100 and see what idea below the hands of fate have handed you.

In a hurry and can’t read through them all? Let us serve you a story starter with our magical adventure idea generator! (Disclaimer: not actually magical.) 

I will try to put out more of these in the future, or expand upon your favorites. Feel free to comment or e-mail us at CosmicCrit@gmail.com if you want more Starfinder tips, tricks and ideas from the Cosmic Crit Crew.
