Suggestion:20081029 Football
Before I start let me say that this is a serious suggestion even though it might seem humorous. What I'm going to suggest is ridiculous and not in genre one bit. This is more of an interesting way of experimenting with how the Urban dead population reacts to a silly addition than any sort of change for the game itself.
I suggest that Kevan place a football (as in a American soccer ball) somewhere outdoors in Malton. The football ball can't be attacked or picked up. However if you're in the room with it you choose which direction to kick it in (N, NE, E, SE, S, SW, W, NW). Kicking it would cost 1AP and move the ball 1 space in that direction. Both zombies and survivors can kick the ball. You'd be able to see the ball from adjacent squares either as "football" (with a font difference to distinguish it from a character) or with some sort of icon.
The current position of the ball would be added to the game stats. Perhaps teams would form to compete moving the ball to different destinations, or "goals." I'm not sure I'd make a point of playing with the ball for long but like where's george it'd be interesting to see where it is.
And while it's out of genre, since it would only exist in one square at a time in ALL of Malton it shouldn't be that disruptive. It'd strikes the same fun balance Christmas trees, Halloween masks, lava lamps and other silly things in the game (ok I made up the lava lamps).
