So, we’re talking about Mike Pondsmith’s original/vintage tabletop RPG work, not the computer adaptations, eh ?

I still have most of those books from the 1990s, and they’re pretty good. The first tier of the bundle features Listen up, you primitive screwheads, which I remember as a pretty good GMing advice compendium. It’s useful beyond the Cyberpunk 2020 TTRPG.

Really, the only downside is that this bundle comes not too long after the Conan TTRPG one, and having too many commercial offers on the homepage makes me self-conscious.

As usual :

• This is an affiliate link. The parties getting a cut are the AbleGamers charity, and Writeups.org.
• You pick a tier, depending upon how much of the bundle you want and how much you want to pay.
• Everything is downloaded, comes DRM-free, and in multiple formats so you can read it using various software.
• At the page linked above you have explanations about the books, and previews of the material.
