It's not overly complicated. You have two teams who each get a flag to defend. The goal of the game is to defend your own flag while also snagging the other team's flag and bringing it back to your base.

[Jason isn't sure if now is the time to elaborate much further, since the purpose of this meeting is a more general gathering of resources and cooperation among everyone.]

There are a few rules beyond that about boundaries, taking prisoners, and no maiming or killing. Obviously.

[As for how many players.]

At minimum? I'd say maybe six...though we usually had far more than that.
