Here's a neat challenge I thought of: #FreeRPG systems in 2023. To me, the spirit of the #TTRPG hobby is getting together with friends & creating great memories; the miniatures, book collections, & extravagant terrain sets are all just window-dressing.
Can you run multiple campaigns only using open source, free systems, or free versions of systems? Games like #Ironsworn, #OSRIC, #Morkborg, #BasicFantasy immediately come to mind. Or free rules from OSE, GURPS, FATE, or even D&D.
