Basically, this would be played like a combination of "hot potato," basketball, and rugby across the entire game-world.
Players join teams, possibly related to the locations where they rent.
Any player can create a Zootball at his or her team's Zoothoop, as long as his/her team has X or less Zootballs in play. The goal is to get as many Zootballs into opponent's Zoothoops during a given day. However, there are certain factors to the game itself:
1) The Zootballs are unstable--after somewhere between five and fifteen minutes, a Zootball will explode, doing mood and energy damage. However, while in your possession, you gain one point of mood per ten seconds.
2) You can only carry one Zootball at a time--if you try to carry a second, *both* explode!
3) A member from any opposition team can steal your Zootball by being in touch with you and interacting with you. He or she gains some mood, you lose some. (of course, that opponent will be even less likely to know how much time is left on a given Zootball...)
4) You can *give* your Zootball to others on your own team, if they want to take it.
5) If you tag an opposing Zoothoop with the ball, the Zootball poofs musically, and the player scores a point, TWO points if it's a stolen Zootball that was made at that hoop! (Possible mood/energy/buff reward for this?)
The following Cool Things evolve from this model:
* The player can get achievements and/or bonuses based on his/her Zootball score from the previous day.
* The players' TEAMS can get achievements and bonuses from winning the prior day's game.
* This gives players an additional reason to interact that DOESN'T focus on the various types of crafting and grinding skills... and, most importantly...
* The advantage goes to the players who *really* know the streets, giving something of an edge to the explorers and lovers of platform games.
* It's also a type of game that allows newbies to play alongside more-skilled people with minimal penalty.
Obviously, the basic idea may need to be refined, but it does give people a different way to interact and play with the basic Glitch world.
