(One of the guys at my wife's work had this idea)
Modified CTF (capture the flag for the slow kids....

)
Im going to try to illustrate this as best I can for clarity's sake
So each team has 3 flags, and the teams flag capture points are on the opposite wall from their spawn:
[spawn(red)] [Red Capture point]
[Red and Blue flags in middle]
[Blue Capture point] [spawn(blue)]
Each team's objective is to capture all the opposing teams flags and keep their own, however you can only capture one of the opposite teams flags at a time, even if you bring your entire team into the flag area you can only return one at a time. This is a simple capture the flag but here's the twist.... You can choose to recapture your own flags from the other teams capture point, same rules apply to capturing these flags too.
If a player is shot with a flag in their hand then they just drop it where they where shot, this way no one team can just camp.
This type of game keeps the game moving because you are constantly deciding between offensively capturing the opposing teams flags or defensively capturing your own flags back.
