What is a D&D Session Zero?+
It is a conversation before play—or a later campaign check-in—where the group aligns on the game, boundaries, character expectations, table practices, and logistics. Its useful output is a set of decisions, not a checked list.
How long should Session Zero take?+
Use the Essential agenda for a short campaign, one-shot, established group, or a quick reset. Use Full when the group is new, the campaign asks for a larger commitment, or the subject matter needs more care. Stop when the important decisions are clear; there is no required duration.
Should everyone share their boundaries with the whole group?+
No. Give people a private route to the GM as well as a group conversation. The shared agreement should record the resulting boundary without naming who requested it or requiring an explanation.
Do we need to agree on every topic?+
No. Mark a topic Not relevant when it genuinely does not affect this game. If the group cannot decide something yet, leave it open and name when the decision will be made instead of pretending it is settled.
Should we revisit Session Zero later?+
Yes. Expectations and comfort can change. Revisit the agreement after the first few sessions, when a new player joins, when the campaign changes direction, or whenever someone asks.
