Got to introduce a new player to RPGs last night using One Shot World. Totally fun! This hack of Dungeon World lives up to its promise of optimizing the game for one shots and making character/setting creation quick and enjoyable.
Started our session with a mid-battle cold open, and the Barbarian dispatched the giant snake enemy with one hit—but that was great, as we got to then see the PCs poke around the creature's cave, interrogate a corpse with Cleric magic, and generally get into shenanigans until the mountain itself started trying to eat them. A good time was had by all.
