Which world size should the host choose?
Choose the lower group size if people may leave early. The world adapts some challenges around the selected number, so choosing 4+ for a group that frequently drops to two can make progress less practical.
Can more people join later?
Yes, up to the 12-player maximum. The official FAQ describes the selected size as a minimum participation expectation rather than the session maximum.
