An occasional #TTRPG thought I have: we lose a lot of gaming history because of licensed materials. I've heard how great the Ghostbusters RPG was. I know and love d6 Star Wars (2e R&E was mine), and have a new appreciation for RM, which I know through MERP.
But because they're licensed properties, they don't exist anymore. Can't reprint, licenses sold to others. Not gone, just rare and hard to get.
Ever since 1984 I have been kicking myself for not picking up a copy of the Ringworld RPG. I thought it could get a copy later. Then it abruptly vanished and the few used copies available are outrageously expensive.
@nyrath About 20 years ago, I was in a used bookstore and ran across an issue of a magazine from the 80s, whose name I don't recall, but was supposed to have rules for playing orcs inside.
I was *dead* broke at the time. The magazine was only 1$, but I really couldn't afford it. And I have lowkey regretted it ever since.
