Would like to hear more about adapting adventures for your game as it is something I would want to do myself, given that I have both a One Page Dungeon Compendium and Dissident Whispers (awating shipping) in print.
Short answer:
- All NPCs/creatures have default abilities of 10, 3 HP, and weapons/attacks as per equipment page
- Replace fantasy weapons with modern weapons as appropriate
- Be prepared to address anachronisms with excuses or editing (e.g., motor boats go faster than assumed boat speed in most swamp adventures)
- Come up with an excuse to be someplace with older architecture/ruins so it’s less obvious to players where you got it
I’ll try to get a blog post up soon with more detailed info!
