Humor, jokes, memes about TTRPGs
Core rules as paperback and PDF. Note that the paperback is a scaled down (6"x8") version of the 8"x11" hardcover which I can't find for sale anymore so only buy that if you're okay with relatively small text.
Drivethru is the publisher's official partner for the digital versions so they have everything that's available. The official wiki has all the rules without the fluff ~~while Wiki Aventurica has world descriptions and a list of available source books..~~
Edit: just found out that the English version of Wiki Aventurica has very little content compared to the German version. The official rules wiki is still usable though.
