I was GMing a game of Dungeon World (a PbtA system) with my friends last year. I had to put the games on hold when real life got in the way, but it's a really fun system. It's kind of old now, but I was deliberately looking for a fleshed-out system that was more or less 'Done,' meaning I wouldn't have to buy another book every 4-6 months to stay current. Anyway, It will be fun to return to it and pick up where we left off.

I also want to run a one-shot of DURF as a palette cleanser sometime down the line. It's a free rules-lite, classless TTRPG weighing in at a whopping 12-pages, and has an elegant way of balancing minimal stats with clever inventory management, a stress system to improve roll results, and encourages planning/provisioning before embarking on adventures (it's more interesting than it sounds).

Based on how that goes I may try to get the group to try Vaults of Vaarn, which is somewhat similar but based on Knave, and is a post-apocalyptic setting with an emphasis on exploration. It also has crazy fungal-people, mutants, and robot/cyborg PCs. It reads a bit like if the games Kenshi, Caves of Qud, and Sable all had a baby, with maybe a dash of Mad Max??

Anyway, some fun systems all around.
