If you have a large group playing, like 8 people, can you take more than the required number of team members on a mission?
Say a mission requires 6, do you have to leave the remaining two players in the Rec Room?
The rules don't seem to make this clear.
I say yes, you must leave them behind. In your example, it is possible to MATCH the requirements. So you must MATCH the number of team members... not exceed.
Here is the wording on page 9 of the rulebook:
2. GATHERING A TEAM
With a Mission Log card revealed, the Captain selects a team to investigate. This team always includes the Captain. The number of players (including the Captain) required for each team is shown on the Mission Log card, as are any departmental requirements. The Captain must choose players matching these requirements when possible. (See page 18 if you cannot meet a requirement.)
