Had not realized there was an issue around the rights of the thing, was there some sort of falling out with Greenbrier Games? There’s a post on the BGG page from the designer announcing it, but that was 4 years ago and at the time he said he was about 60% done with Grimslingers 2. Most recent post from him was June 2022 saying he’s still working on it, but no ETA.
You could say that about literally any library of books, not just RPG books. Even if I myself may not read the books regularly, I still read them at some point, OR potentially I’m like a torchbearer, I’m just taking care of all these books for the day when somebody else discovers them and is able to read them. I may be dead and gone by then, but I’m doing my part to keep the books and the hobby alive.
