Do you want to try some combat without fighting? Have some friendly NPCs that you don't want getting hurt? Or maybe your players have said they want to try something a bit different? Then this might be what you're looking for, an adaptation of Basketball into D&D! It's not a 1:1 adaptation, since even a 10-minute Basketball game would be 100 rounds and D&D has some non-realistic parts, so instead, I've prioritized playability over realism.
