Yanks and Rebels Game
Define a playing area the size of a basketball court or half that size.
This is much like "Giant, Wizard, Elf" but has a game leader that can help bring a close to the game if time runs low.
Divide in 2 teams, one at each endzone.
One team is the YANKS and the other is the REBELS.
The game leader gives out commands which the teams obey, such as "Yanks, 4 steps forward", "Rebels, 5 steps forward", "Yanks, 1 step back", ... This moves the teams closer together and heightens the suspense.
When the teams are close enough, the leader commands, "Yanks, ATTACK!" or "Rebels, ATTACK!" - whichever he wants.
One team must run back to their endzone while the other team tries to tag players. Anyone tagged joins the capturing team for the next round.
