Dungeons and Golems.
Years ago when I played Dungeons and dragons, I wondered whether it was possible for a good fantasy role playing game to have a serious Jewish flavor. I thought about a fantasy universe where heroes went out to kill monsters but also rested on the Sabbath, set time aside for prayer and study, and tried to decide when Pikuach Nefesh issues (surely much more common in FRPG than most people’s real lives) should override halacha.
It may be quite impossible to create a satisfying FRPG along these lines, and maybe that’s a good thing. I still wonder though.
