Ok, the point of this thread is simple in theory, but potentially complex and interesting if more thought is given.
The request: What organized water warfare games do you or would you recommend for others to try which can be completed within 30 minutes to 1 hours total duration?
The time limit does prevent some more epic-sized, epic-length games, but then again, time limits also force participants to take more chances and have more frequent engagements with their opponents.
Feel free to recommend games from the iSoaker.com Water War Games section or outline your own variant of a common game or even describe a new one! The possibilities are endless, but these game ideas should help others decide what to play when they are unsure of what to try.
