Invite only the players needed for the session
The best player group depends on the question you are trying to answer. Bring in the smallest group that can produce the feedback you need.
Keep the invitation path simple
When you share access, include enough context for players to know:
- what they are joining
- when the session starts
- whether voice coordination will happen elsewhere, such as Discord
Reduce friction before the session
If players need extra instructions just to get into the room, fix that before the next test. Joining should feel routine, not like setup trivia.
