D12: the most underused die in the TTRPG armory.
1-in-12: great low-chance target that avoids the rabbit hole of tiny percentages or 1-in-20
Divide by 2 for a d6
Divide by 3 for a d4 (that actually rolls)
Divide by 4 for a d3
Divide by 6 for d2
Why no love?
I should write a d12 game…

Rookie question:
I bought pdfs of 0D&D from DTRPG hoping to print them for personal use through Lulu.com. I found the pdfs are encrypted and Lulu won’t allow me to print them.
Is there a legal way to get physical 0D&D books (besides spending $2,000 on originals)? Thanks

For those who might be interested my lite B/X-adjacent ruleset is available on @drivethrurpg.com for $1 per pdf. Just search “McHack”.
One day I’ll figure out the POD function on DriveThru, but I printed these bad boys off of Lulu (A5 size).

Well, this little set has “seen some action”, as they say, but a very welcome addition to my #OSR #RPG collection: 2nd edition of Marc Miller’s terrific sci-fi game #Traveller!
I loved playing this as a teenager in the 80’s, but wished I’d played more. Looking forward to diving back in.

Most people have an Internal Monologue. The Mog, however, has always had an Internal Theme Tune: Raiders of the Lost Arc. It’s pretty sick, and responsible for my unshakable self esteem.
As sick as that is, I always secretly wished it was the theme to Battle of the Planets. [sigh]
